You said the reason for delaying the PC was extra polish and optimization so the game can run across a wide variety of machines.
What about the PS3? The game is now apparently delayed 2 months after the 360 release. Why is this? Did Microsoft throw money at you guys for timed exclusivity like they did with Activision's Call of Duty map packs and other XBLA titles? Or is this a case of Sony's Quality Control being overly strict, as was the case with Blacklight: Tango Down?
PC users were given a reason for its delay. What about PS3 users?
