Wow, I stayed up too late playing this last night. It's just one map right now and only Rush. Personally, I would've loved to see Conquest first. Maps huge and the controls on the PS3 are similar to the BC2 controls. It looks like the classes are switched around a bit too, as far as gear and specialties.
Still looks like a beta in some aspects, but the animations look great (sliding over walls instead of just straight body jumping, watching knife and gunfire deaths, etc.). The return of prone is cool, but it almost seems like people lay too flat or their bodies stick out in weird directions (once again, beta). It's not hard to tell who's who on console sice there are name tags. If it's showing and it's blue or green--friend. If nothing shows up--kill it with gunfire. Much more varied environments, hard to find snipers. Being capable of only speaking to your squad still bothers me. I want proximity chat or at least some kind of commander position that can talk between squads (kind of like MAG's set-up).
Iron sights are a bitch, you're going to want a scope. And thowing a heavy barrel on there affects drop over distance...lots of attention to detail. Look forward to playing on the PS3 with everyone (looking at you daniel...you shall see my finely tuned analogs in action, and my Snake-like stealth).
