So ... That big third party rumoured exclusive for Xbox1.

According to some people, it's a game that has been off the radar for a while.
My bet is Rainbow 6: Patriots. If I'm correct, that game had some problems during development and had to be developed all over again. It would be typical Microsoft to offer to fund the game while getting exclusivity (or Xbox One and PC) in return.

I will be so pissed if it's Rainbow 6.
