as much as the cancellation of Scalebound seems like a mega hit to the Xbox (considering the limited solid exclusive IPs), there is obviously probably a reason the project was canceled. I.e. totally different visions on the game. We don't know who is really to blame, more Microsoft or Platinum
in the end Microsoft has more money than practically any other company out there, and they're used to throwing away loads of money on the Xbox (has the platform ever made them money? like overall, their video game division?, sometimes I think the Xbox is just a marketing tool for them to keep Microsoft in the mind of younger generations, because their money seems to come almost exclusively from their programs, i.e. Microsoft Office, Windows).
Just don't see a realistic reason Microsoft, again loaded with cash, would bail on Scalebound unless the project was not going nearly as well as the clips shown looked. The game LOOKED far along, but maybe that was deceiving and just to excite fans (what bits were shown being worked on more than the rest of the game I mean)
the automatic reaction is "oh yeah, Sony should pick this one up and the Playstation will become even more dominant in terms of exclusives". But even if they were capable of buying the IP from Microsoft the odds are genuinly that Scalebound is a mess and far from finished.
I think a lot of you are jumping the gun here. There is no way Microsoft canceled a project that was near finished OR coming along well.
