It's built around the Vita's controls, not just the touch-screen, so they probably won't be able to port it so easily, I'd imagine...
As far as liking the YouTube video goes, I'm honestly not too sure it'd make much difference to Sony's handling of the series, unfortunately. This game being both digital-only (when the reality still currently is that the majority of presence is at retail - when's the last time you saw a "big name" game go digital-only?), and on a system with barely any install-base, probably won't help matters, either. Still, I remain hopeful that they really have committed to doing something more with the series now than just license-squatting.
