(also around 2:15 you can hear a remake of the SC1 Protoss briefing room music)
I was a little afraid of things just being exactly the same as Heroes of the Storm's UI, but I'm really liking this. Things like showing a marine, zealot or hydralisk depending on the race you're picking is fun, and chat looks great, though, tbh, it's what it should have looked like 5 years ago. And it feels right that they're really making the campaign section look like Starcraft 2 as a unified game, with the 3 sections portrayed the same way as the racial campaigns in SC1.
