Command & Conquer Generals 2... with frostbite 2, and being developed by bioware... Sounds like a beastly combination. Wasn't a huge fan of generals, but generals 2 has got me psyched. Hope it does well. I cant wait.
If you look closely you can see the usual jaggies that come from in-game stuff, so yeah I doubt it's pre-rendered (atleast not like that Killzone 2 trailer :P)
