You mean, the reality in which I'll be playing Rise of the Tomb Raider and you won't?
C'mon, some people prefer PS4, some prefer Xbox One. Each get their exclusives. I own an Xbox One and like to get exclusive stuff, and I don't go on facebook and twitter everytime something is announced on another console because I won't get to play it.
Game was slated for end of 2015 and all that was shown was a CG trailer. Do people really think the game was far along in development? As far as we know, game got announced with CG trailer, CD/SE talked to Microsoft, exclusive deal was made, that's it! Everything else is just people pretending the game was coming to all systems, it was never announced for other systems as far as I am aware, except for people taking it as granted.
