People always calling for Nintendo to go software only but they wont. They have so much money in the bank they can afford to do these "experimental" consoles and risk them fail. They have enough money to release 3 generations of failed consoles and still be in profit to make a 4th! Microsoft or Sony cant dream of doing something like that.
Nintendo also shaped the way gaming is played today. Start, select, back buttons, analog stick, rumble controls, multiplayer controller ports, battery back-up saves. Where would the console/gaming world be if Nintendo wasn't around? They saved the gaming industry from the video game crash of 1983. So let them carry on with their low powered console which dont compete with the high end. If they want to release a 4K gaming console power house then they can but they have no reason to as along as their back pockets can maintain it. You don't see MS or Sony bring anything innovate to the gaming world (Sega tried), they try and copy Nintendo's idea's then fail, Kinect, PS Move, Eyetoy, PS Vita and PSP. So instead they just live of Call of Duty and Fifa every year.
