BF3Blog has a video shot off a monitor at PAX East showing off gameplay in the upcoming Close Encounters DLC for Battlefield 3, the military shooter sequel. The clip shows off the claustrophobic indoor combat the new DLC will add.
To be honest, sometimes I do feel like playing close quarters and there is VERY few good ones in BF3, so I don't get what the hate is all about. Nobody forces you to buy or play this, but some people do like to play both "worlds" sometimes, and I for one love no-vehicle maps every now and then.
Also BF3 is superior to COD in all regards, weapon feel, movement feel, fluidity and fun. Now hopefully these maps block engineers though because if not this is gonna be a stupid RPG spamfest particularly if there is a rush mode on these
