Actual servers don't go up till the 25th. But lookin' at the upgrades and what not looks like they have the classic BF classes in it (med/snipe/assault/anti/spec). What i think kind of sucks is 2 upgrades for each class can only be bought through XBL, well 1 of each class is actually obtainable through purchasing "Battlefield Bad Company: Gold"...
Dunno how the gameplay is going to be for the Beta because playin just the how to video of the new gametype the video was really stringy and lagged a lot.
