Shigeru Miyamoto has been fielding questions on the Wii U console/controller/platform that Nintendo revealed at E3 this week. One of the main points covered was just how many Wii U controllers can be used.
He sort of explained, "Our basic premise is that you can use one with a system. If we got to an idea of having multiple (controllers) it might be just more convenient for people to use their Nintendo 3DS and have a way to connect that."
Not to be stopped in his tracks there, however, the great one continued, "That being said, we are doing research about if someone brings their controller to their friends house and they want to play together on Wii U to whether or not something like that would be possible."
He also explains some of the technology underlying the Wii U, "Because of the way we've designed the game system, where the controller is really just that — it does have a screen but it doesn't have a processor inside it.
"All of the processing is happening inside the hardware itself, and then the hardware is sending the information to the controller with incredibly low latency because of the wireless beam we're using. It would be very difficult for the other hardware systems to be able to implement this at this stage."
