-Being able to read DVDs. At this point, the technology for that has to be cheap and easy to do.
-A bigger inner memory. 32 gb are going to be ridiculous entering the next gen. At least 200-300 gb minimum.
-Stop multiplying the controllers: there's the GamePad, the Wiimote and nunchuck, the classic controller wii, the pro controller wiiu, the GC adaptor... I'm not saying that they should stop supporting them, but they might prefer making only one controller and sticking with it.
