PS3 + Vita + FFXIV

[Andrien]

Wii U Controller -> exactly the same number of buttons like PS3 controller -> much bigger touchscreen for chatting, drag and drop etc..

the Wii U controller supports streaming, a bigger display... and the wii u recognize on which part of the screen you are holding the tablet controller in front of it. that part is visualized on the tablet then (to aim through the display)

With all that said, the Wii U gamepad itself still has less features than the Vita.
