Dead space I reckon. They can't really afford to buy out really big franchises, and TR is not what it once was and is really in a rebuilding phase. RE is similar but I think MS wouldn't go there unless RE7 turns the franchise around. At least not for a numbered sequel, an exclusive spin off game is definitely on the cards.
If MS pursues a policy of making established multiplat franchises exclusive they deserve severe criticism from the gaming media for spending boatloads of cash on sequels instead of investing in new IP. Buy exclusive access to new IP ffs, that's how gaming moves forward, sharing risk on new stuff, not shutting off access to old stuff.
