Sony potentially no longer having CoD could be pretty big when it comes to console sales, though Microsoft have been quite open to getting their exclusive stuff onto other platforms so maybe it wouldn't be an Xbox exclusive?
Microsoft's whole console business has always been about BUYING THE TALENT THEY DON'T HAVE INTERNALLY so what's new. I'm just pleased that they keep buying companies I have ZERO interest in. I don't think I've played a Blizzard or Activision game since the NINETIES.
