Being a long-time PC Battlefield fan, this announcement is not reassuring. I've long since stopped playing BC2. I'm playing BF2 and enjoying as much as ever with PR mod. If BF3 sounds like BC3 then I simply won't buy it.
Oh and by the way, the Battlefield games have never had lean. Prone, dedicated servers, a mouse-native UI, commander role, squad leader role, vehicles, planes, tanks jeeps, etc etc etc.. Oh and the ArmA series is not a substitute for a real modern Battlefield game.
Perpetual debt is slavery.
