All things considered, and I really do mean all things...
Yeah it could happen. I would say 2014 is more likely personally.
The thing is Wii still has so much untapped potential when you add in Motion plus and the ballance board, possibly even another periferal at E3. Sports Resort and Motion Plus were both huge successes, there is a strategic chance that the reason we haven`t seen any megaton advanced real motion game designs from Nintendo is that they`ve been saving them for a period like this when the competition is gaining momentum.
Makes more sense than upgrading the Wii. Nintendo is a software dev first and thier games are still selling tens of millions of copies. The only way it would make any sense is if Ninty has another piece of game changing hardware like the wiimote up thier sleeve that everyone on earth is going to want to buy... Even then though theres no rush just yet and Nintendo is all about taking thier time.
