A360 type controller would suck. The D-pad for those controllers are terrible for fighting games which is mostly what I play. >_> Dualshock has always been the best controller for fighting games besides arcade sticks. I really hope the PS4s controller is decent. I've already heard bad things about the Vitas D-pad for fighting games.
You use a dpad for fighting games? At least upgrade to a fighting stick. Heck, I have a brand new one I am trying to sell right now...
I have to say this though, if I was to get back into playing fighting games, I would use a hitbox. I tried one for a couple of hours, and wow...they are great!
The PS d-pad is good enough for fighting games, arcade sticks aren't usually cheap

They should make the next controller modular, so you can swap the D-Pad/Analog Sticks/Buttons to whatever custom layout you want. In addition, you could split the controller in half to use like the move for motion controls, or even dock a touch screen inbetween them if you want.
