As we guessed, Rise of the Tomb Raider will be a limited or timed exclusive for the Xbox One.
Xbox boss Phil Spencer has confirmed to Eurogamer that Microsoft’s controversial exclusivity deal for Rise of the Tomb Raider “has a duration”.
However, he declined to confirm how long that duration is set for.
Our guess is a 6 month window. How much Microsoft paid for this is anyones guess. Expect an April 2016 release with Crystal Dynamics gushing in PR "We always intended to share our creative vision to our loyal PS and PC fanbase"
