Halo is also releaseing on PC.... and they wont rule out "other competing platforms" either.
To me this says, MS has stopped careing about hardware sales.
As long as they sell the game + service, they dont care where its sold.

And, it makes sense. Consoles sales are notorious money losers. Why not let someone else make (or lose) a few pennies on hardware, while you make recurring subscription revenue?
