No need to phone in the shock police -- you had to know this was coming. After all, what kind of stockholder-pleasing company would Nintendo be if it wasn't already thinking about how to top the Wii? According to information in a recent Forbes piece surveying the field of gaming consoles, Nintendo is "already working on the Wii's successor." President Satoru Iwata shared that the Big N was "always preparing for the next hardware," though it would be unwise to expect said hardware anytime soon. With Wii consoles still hard (or at least not "easy") to come by in some locales, we'd say Nintendo is in no hurry to move beyond its current cash cow. Still, even Iwata admits that it "will be difficult" to exceed expectations now that the Wii has proven so successful. Not really, though -- throw in high-def support and you've got an entirely more lovable machine.
