I don't give a stuff about who ripped off of who's controller. As long as it's comfortable, and the buttons and sticks are in logical spots, I'm good.
I remember reading an issue of Game Informer, some guy had this concept for a controller. Kind of like a hybrid of the 360's and the PS3's, using the best features from both. Then there was a small touch screen where Start/Select are, and that could be used to like display achievements, or friends online or something. In fact, the PS4 controller reminds me of this concept. I'll try to find it later. It was pretty cool.
