Wipeout 2048 doesn't work, but for those who have played it, touch screen is only required to choose the races. Remember how the Vita UI and keyboard was touch screen only, and after a patch you can now control those features with buttons? Certain games will probably receive patches to work on the PS Vita TV. The PS4 controller may even utilize the touch pad as the touch screen in certain games.
Since the touch pad is clickable, touching the PS4 touch pad on the PS Vita TV could place a cursor on screen where you're going to touch, and then you click to virtually touch the screen. After clicking, until your finger is removed from the touch pad, it recognizes you as still touching the screen, so throwing grenades on Uncharted, or doing the charcoal rubbings, etc. That would work well. Unfortunately games requiring the back touch pad wouldn't work unless you could change the touch pad on the PS4 controller to be onoe or the other.
