Battlefield 3? Hell yes. Scheduled for release in fall 2011, this game will definitely be a buy for me on PC after enjoying Battlefield: Bad Company 2 so much.
-64 players (PC)
-Settings in areas like New York, Paris, and more open areas for vehicular warfare.
-The return of several Battlefield 2 maps
More info here, including a teaser.
All in all, I can't wait.
