Right now, the Wii is riding a wave of positive public perception, selling out everything else and introducing a vast new audience into games. One that could potentially grow to match or dwarf the current group. The conventional wisdom in some circles is that this success will be short lived. That in a couple of years when the 360 and PS3 are cheaper, these new players will start to look at those systems, which will win out in the long run as this new audience matures into "true" gamers. I don't really see that happening.

Someone introduced to games on the Wii will have a very different perception of "traditional" controls than today's gamer. Nintendo has its own "twin analog+face and shoulder buttons" controller. However, they call it the "Classic" controller, meant for older games from bygone systems. Those raised on Wii are going to see the pointing function, motion detection, and fewer buttons as the norm. When they decide to upgrade, they're going to want a system that includes those basic functions and improves on them. Perhaps true 3D position detection, or a built-in camera, or a wireless nunchuk, or a touchscreen for your coffee table.

To them, the PS3 and 360 controllers are going to be as intimidating and unintuitive as they have been since the PS2 and xbox, or PS1 and N64, or possibly even as far back as the SNES. So they'll simply wait for the Wii's successor.
