IMO, true exclusivity would be preferable to "Here's 85% of this up front for 100% of the cost. You can have the other 15% next year". If I wanted to play the game that bad, I'd get a second system. I'm considering it anyway because PS has some [i]actual[/i] exclusives I'm interested in. Even though this doesn't affect you immediately, you should be concerned. If it proves to be financially successful, I can almost guarantee you'll find yourself on the other side at some point.
