IF the system is a home/portable "hybrid" like rumors say, then yes, I want something like the GamePad back, just sleeker, because that's the onlything that makes sense. The controller would also BE the portable part of the system. Basically just a Gamepad you can actually take out of the house.
If it's not going to be a hybrid, and just a home console, then I'd be fine going back to something more akin to a SNES controller with analog sticks. Granted, the Wiimote setup WAS ideal for FPS games. But otherwise, I wouldn't miss motion controls. I personally LIKE the GamePad, in spite of it's bulk, and think it's a cool controller. I like being able to play games Off-Screen, and the touch screen is super convenient, etc.
In other words, I'll be fine with whatever they do, GamePad concept or not. JUST so long as the new controller is super stupid looking, and the system doesn't have any dumb gimmicks (like VR). Just so long as it's not retarded expensive, and has good games (and an even better eShop), I'll be ok.
But I STILL don't want it to come out till 2017.
