What you would like to see in the expansions?

[TheEconomist]

Zerg art redo, Zerg sound redo ...

BAMF campaign!

[limE]

Micro heavy units.

[TheEconomist]

a set of units and buildings for the Xel`Naga in each part of the game, so we can put together a 4th multyplayer race in Legacy of the Void

Never going to happen.

[FoxSpirit]

More units, especially Zerg. Also, more flexibility on them. Would be nice, Terran is just such a great utility race in comparison.

[GnaReffotsirk]

A unit that can break apart a ball of units. It doesn't have to be like what we already know, and I'm sure they can come up with something of the sort.

[Twilice]

An epic campaign and ALOT of more b.net 2.0 features.

*also a wc3 like version of the editor for an easier way to create new units. And the option to switch to the advanced.

[GuaiLow]

LAN SUPPORT!!! and more units.

[Blazur]

Spectres and Reavers!

[dustinbrowder]

We know whats coming with single player so I'll focus on MP and bnet.

I'd like to see 3 new units for 1 removed from each race.

For the Terran specifically I'd like to see 2 units that can combine themself and become a bigger and more powerful one.
I'd also like to see megatron introduced into MP as a single unit also.

I'd like reworked unit dialogue and sounds, more tilesets and a new gameplay mode.

For Battle.net 2.0 I'd like to see group replay watching, global broadcasting in real time, TV profiles and channels, integrated internet explorer, custom ladders, maps bigger than 256x256, global integrated page for tournaments and custom tournaments.

No more broodwar units plox. If they are going to add units make, they should make something new and original.

Hopefully they'll have cross-regional play by then.
