Definitely a good thing to boost their console exclusives.  It'll be business as usual for me as most of their stuff is what I play on PC anyways, and these will all be on PC no matter what, but some of them going Xbox only is kinda significant.  I also don't think they'll make everything exclusive though, because losing the Playstation market is a pretty big market to lose.  Like I could see some of their biggest games like Elder Scrolls being on a timed exclusivity before coming to Playstation perhaps, but we'll have to wait and see.
