I just hope that the final version of BF3 for PC has a few extras and bonuses with gameplay and graphics that will make it all ok. They can favor the PC's it is ok to do it. Xbox is favored when it comes to DLC's. They always get them first it seems, so it is ok for Dice and EA to favor the PC.
PC will have 64v64 consoles have 24v24 (or something)
Better graphics and controls
Dedicated servers (mods tools hopefully to follow)
Can't think of anything else right now but the game will just be a lot bigger for the PC.
