Don't be daft. If its not, then this is the greatest troll of all time, which has managed to befuddle some of Neogaf's greatest informants. What are you doing in this thread, other than shitting it up with nonsense? Its 99% likely to be Demon's Souls 2, and therefor Sony exclusive. Let's all start coping with that fact and stop any sort of thinly-veiled "could be" trolling. Anything, however absurd, is a possibility given the infinite chaos and permutations of reality.
Maybe MS is making a multiplatform Halo. Maybe Sony sunk 50m into a Haze reboot. Maybe Nintendo's QQL stuff is a Princess Peach branded dildo. Who knows? Let's talk about what is probable, given the information at hand. It is probably that this is Demon's Souls 2. The end. Let's base our discussions and potential debates around that.
