As long Xbox One "exclusives" end up on PC too, I'm good. Titanfall looks like a good game with some cool ideas, but I'm not too big on multiplayer.
About that exclusivity thing, multiplayer games benefit from being on as many platforms as possible since having your friends playing that game is an incentive to get that specific game yourself.
Mass Effect (first one) was published by Microsoft itself but was released on the PS3 later. Not the same scenario, I know, but as long as it is not a first party title, there's always a chance it will end up on the other platform.
