Did you miss the 2nd part of the Microsoft statement? "We can't comment on the deals made by our partners with other platform holders,"That's what makes this whole thing weird to me, the Game Science statement on the delay. They could have lied, certainly, it's just bizarre!
And Microsoft technically didn't even refute it! They said they're working with Game Science on bring the game to Xbox. Which is a weird thing to say when it was already advertised as coming to Xbox!
Why would Microsoft say that if there's no exclusivity deal between Sony and Game Science?
Clearly Microsoft got wind of something if they added that to their statement. Like, this is easily refutable by Sony/Game Science if there's no exclusivity deal.
