From what we're told, the PC and console versions of the game will be identical aside from the graphic and control issues that I had mentioned earlier. The only addition from a content angle will be the possibility of added multiplayer maps for PC players that seem to chew up new multiplayer FPSs a bit quicker than console gamers at this point. There's always the possibility of an extra weapon, but that hasn't been seriously discussed at this point. There's a high likelihood that something like this wouldn't even happen.
