This would be perfect on the Vita

When the game switched from Kojima Productions to Platinum Games I thought they took out the ability to control your slicing. Now taht we know that it's back in wouldn't this be perfect for the Vita's touchscreen mechanics. Rather than holding R1 and flicking with the right stick, all you'll have to do is tap the screen and flick your fingers on the screen.

Remember the rumors of the Move or Kinect being used for Rising, I think touch screen would be better.
