Alguna info sacada de gameinformer en ingles:
Gameinformer, about BF3:
-Specs and Customization
-There will be a kill-cam (but it can be turned off)
-4 classes, meaning all kit weapons is a confirmed
-Will have co-op
-Single player
-No mod tools at release. Maybe none down the line either.
-Health regeneration (No HP values displayed)
-Frostbite 2.0 is the culmination of this tech, entirely re-written, which is based on Frostbite engine, specifically developed for Console games such as BC1/2 a.k.a. BF Bad Console series
-Future/Modern Setting in 2014, just as in BC2 which had a future/modern setting, with motion sensors, tracers etc
-You play as a soldier in the United States army, just as in BC2
-The Cover Art is a throwback at BC2 (BC2 cloning some key elements from the CoD series), which IMO is hilarious, because you would have thought it would have been a throwback to BF2 with the cover, or something at least (Even though Vietnam/1942 cover were far superior artistically to anything made by DICE to date, and IMO even BC2/BC2 Vietnam with it's original idea of inner fire and very contrasty people/tanks/etc, a throwback at 1942 would have been nice)...
-Patrick Bach doesn't like the idea of commander, and wants the same things as in BC2 (Uav to all, classes are like mini commanders)
-Possible hardcore, even more hardcore this time around
