1up cites a tweet from Infinity Ward's Robert Bowling that says, "if you bought a retail copy on PC, you can play it on 11.10.09." The tweet was in response to a user who asked, "Will we be able to buy and play #MW2 for PC on 11.10.09 or do we have to wait until Friday for steam to unlock the discs?"
GameStop made headlines this weekend when it broke the November 10 street date for Modern Warfare 2. The retailer initially said it had Activision's permission to release the game ahead of Tuesday's launch but later changed its story when Activision denied the claims. GameStop now says the decision to release the game was a corporate one and says it is only selling MW2 in markets where the street date has already been broken.
