Well the capacity is higher, but I believe things like it have existed for awhile. I could be mistaken.
The only systems I ever have are Playstations. Not cause I have brand name loyalty..... simply cause I have held a PS controller since I was in highschool so I know it and it feels right in my hands.
They ever really change the controller Im out.

The PS4 controller is a little different but only small changes, I can live with that.
Im not much of a gamer short of a few rare games here and there...... so the last thing I want to do is learn a new controller for something I just turn to as a last resort for entertainment.
Wii IMO was more of a novelty.... I dated a woman that owned one and it was fun and Im sure amusing watching me shadow box while playing a boxing game.... but after playing with it for a short time and learning that the controller simply needed a slight tilt for the same effect...... the novelty wore off.
When I actually have to bob and weave, jab and upper cut in a boxing game..... sign me up. Til then....
