Whenever there's some kind of leak about a Microsoft product, whether it's legitimate or completely unfounded and false, Microsoft's response is always and every time exactly the same:
“Microsoft does not comment on rumors and speculation.”
I've often wondered why NFL teams don't treat the draft the exact same way. Why tip your hand? And if people think that certain actions tip your hand, just give a stock reply to EVERY inquiry about players your team may or may not be interested in. It just seems like the prudent thing to do if you want to keep other teams guessing.
