John Lucas,
There will be no "Wii 2." Nintendo will move to their next console when they have new, disruptive, audience-expanding ideas which they cannot accomplish with Wii.
While developing things like Wii Sports and Wii Fit, it's only natural they'll come upon things they can't do with Wii. We know that Nintendo holds onto ideas, sometimes for decades, until they can implement them properly. Miis were a concept in the 80s, and both Pikmin and Super Mario Galaxy spring from the infamous "Mario 128" project. Franchises like Zelda and Metroid have gone without iterations for 7 or 8 years, only to return with landmarks like Ocarina and Prime.
They aren't about to stop coming up with new gameplay concepts. They'll probably come up with more than anyone ever has before. And they won't be able to implement them all on Wii.
No, they won't release a virtual reality whatsamacallit. Not until they can make it look inviting and fun, without helmets and all sorts of sensers. Everyone wants to jump to this ultimate conclusion of gaming as 'virtual reality,' but Wii Sports and Wii Fit really aren't linear steps towards that conclusion. They are another thing entirely.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
