This is the end game as I see it and I'm pretty convinced this is what Microsoft is planning for. If that's the way it goes, they have a huge head start over Apple who are insisting on keeping OSX and iOS separate. I don't see much of an advantage for Microsoft here. Metro is another world than the traditional desktop, and Metro applications are only really fit for tablets and phones. So, a hybrid will probably keep a desktop/tablet UI separation. Since iOS and OS X build on the same technologies, Apple could, if they wanted to, release a hybrid system in no time. In fact, the iPhone/iPad simulator already uses Cocoa Touch on the same architecture and platform as OS X. Besides that, Apple has an App Store filled with tablet apps and desktop apps. Not just tablet apps.
