Personally, I think both MS and Sony will have a third-party exclusive each (at least one anyway, there won't be many, but perhaps one or the other will 2) to announce this year, I think that game is definitely on.
For my thoughts on it, if they're going to save a title in trouble/having difficulties (Titanfall, Dead Rising 3) then I'm all for that because it gives me a game I wouldn't necessarily get otherwise they're spending money and I'm actually getting a benefit, or perhaps it wouldn't be quite the same game.
I don't know the exact circumstances of something like Tomb Raider and Street Fighter V but I largely think neither me as a PS4 owner or Xbox One owner probably gained much from either of those investments from Sony or Microsoft, I doubt we will ever find out the reality anyway.
