In a Forbes interview published Tuesday, Nintendo President Satoru Iwata freely admitted the company is already working on new hardware.

Don't go thinking that the revelation means a Wii successor is coming anytime soon, however, as Iwata said he doesn't view video game hardware as "particularly interesting."

"We are always preparing for the next hardware," Iwata said. "We are under development. ... But the hardware is a kind of box that consumers reluctantly buy in order to play our games."

So don't expect any more details about that for a long while, especially since Nintendo just made more money on software over the past year than its two main competitors, Sony and Microsoft, combined.

Iwata was worried about one issue, however: How Nintendo would surprise gamers and the gaming industry as utterly and totally as it has done with both the DS and Wii.

"Every hardware needs some revolutionary features," Iwata said. "This time around, it happened to be we had a revolutionary user interface. Will it be the same for the next generation? I really can't tell.

"It's natural for the current customer to expect Nintendo is going to once again do something different," he continues. "If the people are expecting so many different things from Nintendo, it's going to be difficult for us to go beyond that expectation again."

Nintendo was not immediately available for further comment when contacted on Wednesday.
