Did Microsoft Accidentally Confirm a PlayStation-Exclusive Superman Game?

Microsoft's reference to a "Superman" game as a PlayStation exclusive in a recent document is likely a mistake, and they probably meant Insomniac's Spider-Man games. The document also mentions Sony Santa Monica's God of War as a "big title" for PlayStation, implying that the game is already out. This is just the latest in a long line of silly developments around Microsoft's attempted acquisition of Activision Blizzard.
