Like John Riccitiello said, it's really hard to discern the difference between the console version and PC. There are actually some clips of the console version in the Frostbite 2 features video:

0:45 - PS3 0:53 - PS3

Additionally, the Operation Metro trailer appears to be on the PC, as it states that "R" is reload, but they might have stuck in some console gameplay, like in the Frostbite 2 trailer.
