Check out this Gamesradar article. They claim they have got it all figured out. I´m not so sure, but see for yourself.
I have tried to trace this story up and I must come to the conclusion that Gamesradar has been a tad over-zealous here. Of course, I can´t be sure. But I have tried to find the patent on the U.S. Patent Office site, without any luck. Also, why don´t they simply link to the patent in question or, at least, mention either name or number? It´s very suspicious and not much to do with journalism I must say.
Lastly, it mentions a touch-screen. This has been specifically ruled out by either Iwata or Reggie at the press conference. Haptic screens fine, but no touch-screen. I just don´t see the revolution in this patent.
