It sure is strange with the Wii. People say its bad them selling so many as sales will peak in 2 years and they will be overtaken by the next gen boxes.
Then again, if the Wii didn't sell people would ask why it was brought out. If Nintendo build up a strong following with the Wii then bring out a next gen box with backward compatibility in a few years it would be a hard combo to beat imho.
You're probably right donta - its all about marketing...
