I wouldn't be surprised if this deal was made back when they were developing DR3. They probably knew Capcom was going to do the same thing as they did last gen, release the 1st as an exclusive, then the 2nd as a multiplat. So, MS most likely worked out a deal with them to at least make the 2nd one of the gen a timed exclusive. That's what I'm guessing, anyway, since you would be a complete idiot to ignore a fanbase that will be ~50M strong by the time your game comes out. Especially since the PS4 may be seeing a few great zombie games launch next year that will pull interest away from their game.
