Can anyone tell me where this info is from and if it's canon or not?

My thoughts would be that you couldn't use the grav generator to bypass the seige mode, because increasing gravity enough to withstand the shock would lower the veolcity of the shell if not just crush the seige tank altogether, and kill its pilot.

It didn't crush the tank when they used it to move under the massive tornado, much less to just fire the tank's main weapon.
I think we can assume than the tank's weapons won't be affected by the gravity generators. The crew certainly isn't.

It would allow a Siege Tank to quickly fire it's main weapon without going into Siege mode. Even if for extended shooting, siege mode would be more energy-friendly, if they use it in the case of loss of gravity, that means it could be sustained for a good amount of time at normal levels. If someone can modify the generators, others will, if it's a good enough idea.

As the passage notes and which Pando pointed out, it's only good enough to simulate regular gravity; it's why Marine suits could have them but still be prone to getting knocked on their asses. So trying to fire the shock cannon with only the generator on would be the same as firing it on Earth without the supports, in other words Bad Things Happen.

This tank was rare, it could simulate a higher gravity field and keep its crew from going squish at the same time. I would imagine it's also much more energy intensive than normal grav generators, which is one of the advantages of having mechanical struts: if the power to them goes down, they don't stop working.

And what's wrong with the Banshee? It's by far one of the more practical designs for the Terrans, especially compared to their Veritech fighter wannabes.

Ok, let's assume you fight with your very energy efficient Siege Tanks that take some minutes to switch modes, while i fight with modified Siege Tanks that can fire the big cannon just slowing down, then continue moving. Who you think is going to win the battle?

No gravity = no atmosphere. I wouldn't want to be flying on a ship that will fall like a rock if gravity goes off.

Its not a ship, it's a futuristic helicoptor, and it fits its role perfectly. You have Wraiths and Vikings for space combat.

So, the Tanks that are on ground vehicles have gravity generators, just in case gravity goes off, but it's ok to start using helicopters there? How does that make any sense?

You can have an atmosphere, without having gravity. (Ie. like the inside of modern day spacestation or shuttle)
Also vice versa - The moon for example has no atmosphere, but it does have gravity. (albeit very low gravity)

Also if the gravity fails, it wouldn't "fall like a rock", but rather continue in whatever direction and speed it was travelling at when gravity failed.

A propeller needs an atmosphere in order to be able to provide lift, not nessesarily gravity. Just like birds would be able to fly: http://animals.howstuffworks.com/ani....htm/printable (Similar things are said on NASA's sites, this one just discribes it better)

So I personally take it literally when blizzard calls it a planetary craft. But they obviously can't leave it out of spaceplanetform maps. I wonder if it won't be available in singleplayer on such maps?

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

They made a bit of an error there though, turbofans are a type jetengines.
The banshee is closer to the V22 Osprey.

*edit* Disclaimer: I should mention that I'm all for the "rule of cool" and as such, this post (and similar posts in general) should be treated as nothing but hot air.

You mean that it contains breathable gases, like if it was a gas tube, but that isn't an atmosphere by definition.
Atmospheres are pulled by gravity to the planet's surface. Unless the space platforms have a huge dome around them, that's how it must work.

Also vice versa - The moon for example has no atmosphere, but it does have gravity. (albeit very low gravity)

Yep, if gravity is low enough, the atmosphere goes away.

Also if the gravity fails, it wouldn't "fall like a rock", but rather continue in whatever direction and speed it was travelling at when gravity failed.

That's true, it depends on the rate of failure of gravity vs atmosphere. If the gravity fails instantaneusly and the atmosphere lasts a little, the unit could be thrown into space. Fun to watch

Yep, and the rule of cool designs the ships . I think it's ok, but also they should be more careful with their lore, you shouldn't introduce some sort of helicopter, if you previously said than Tanks, and most other equipment (even Marine suits) have gravity generators "just in case".

You assume you can make one that doesn't have to stop but just "slows down" to use the main cannon; even with the altered gravity generator, the special tank in Uprising still had to use its supports in order to deploy the shock cannon. Which either means A) the shock cannon is just that god damn l33t B)some inherent design flaw prevents the two from working together C)it only has limited power and can't be used indefinitely.

Do you complain that an Apache sucks, because you couldn't use it to fight on the Moon? Different vehicles have different design parameters. If you're fighting in space, you aren't going to use a heli, you'll use a spaceship.

The tanks were an old design. Those anti-grav generators, which by the way were not rare, were used so infrequently they were forgotten. In short, gravity generators on space platforms are really reliable.

Kerrigan has some on Char Aleph (see StarCraft: Hybrid) and they're still functional without technicians to maintain them.

The tank's gravity generator only affected the "outside" of the tank. There was nothing to indicate that it's weapon could fire without the regular supports. It still needed to transform to siege mode.

So, those anti-grav generators are generally a waste of resources, that's why banshees don't have them. To be cheaper.

No way, if it could move under the huge tornado, it wouldn't go flying from using the main cannon, nor would need to stop completely. Even if it needed to stop completely, it's faster to use than deploying a slow mechanical device.

Probably the best explanation would be that there isn't enough energy to shoot the cannon, and keep 6x gravity at the same time, but even then, it's strange that there's enough energy to keep 6x gravity and move under 6x gravity and a huge tornado at the same time...

No, but we don't use the Apache there, either -_-;

Anyways, i would assume that Terrans won't be so stupid to use Banshees on space platforms, even if that's the case in-game. But that doesn't makes the unit's model precisely a good idea, if it's going to be seen in such scenarios, specially taking into account the fact of all other units being designed to resist gravity outages, as a great concern.
