Servers weren't up in the US when the Beta was initially released. They're up and running and stats now work properly.
I personally hated BFBC1 because it really strayed from the original Battlefield formula. This game feels more like a real Battlefield game. It plays out much more tactically (probably the most tactical shooter I have played on a console) but the weapon damage may be a bit too high. Also, you can't really tell how damaged you are (even when your screen isn't red anymore) so I think they need to add a health bar so that people will actually look for medics.
