From what I've heard this isn't for sure as of yet, and will likely start with smaller titles, not AAA.
If it does happen I'd be willing to bet Titanfall is the first mulitplayer AAA to do it given it's going to run on Azure servers
This is cool though, still got a couple buddies on Playstation, would be cool if they could come game with the rest of our friends.
Looks like I picked the perfect time to make the move to PC as well
