Thanks for the reply.
I'm on PS3. Operation Metro is apparently the least Battlefield-y map in the game, but I'm not sure that DICE choosing that map for this beta really signifies anything. They don't need to fool CoD players with an infantry-only map in order to win them over. And even if that is what they're trying to do, so what? Also, for what it's worth I'm not a huge fan of this map either. But I'm not judging the whole game based on that.
Anyway, BC2 has it's fair share of infantry-only maps, all of which are extremely fast-paced - see Arica Harbour Conquest or Cold War Rush as examples. Both those maps are way more fast-paced than Metro, and they're not the only ones. Faster/no vehicles doesn't mean more like CoD.
The gunplay is nothing like CoD. There's nowhere near the same level of aim assist for a start. It's very similar to BC2's gunplay, with added prone, more recoil and seemingly reduced aim assist.
Levelling up was displayed on the screen in BC2 - ranks, unlocks, badges, ribbons - everything. Perhaps because there was less to unlock, it wasn't as noticeable.
In my opinion, it's not just vehicles that make a BF game, anyway. It's things like the squad spawn, the way the classes interact with each other, the spotting and all the other things that facilitate teamwork. I wouldn't worry just yet, I'm sure this will be a Battlefield experience through and through.
