Bottom line... this game is orgasmic.
Been mostly playing support and engineer, and the action is fantastic, fun, and frantic. Honestly, it feels like a hybrid of BF2 and BC2. The maps are pretty good as well, and I've seen packs of people working great together even when they're not in the same squad.
The only thing I wasn't too attached to was flying jets. The fact they can't drop bombs like they could in BF2 seems to have killed a lot of their effectiveness, and they're really just there for fun and don't really make that significant of an impact on the game.
