The wii prototype was....
NOW YOU'RE PLAYING WITH POWER!
The wii is not a prototype?! what the heck do you mean by that anyway?
Nintendo has nearly 5 million wii units in peoples homes in 4 months. Thats one hell of a market to exploit/make money from. Its taken years of devlopment to get the wii out on shelves. Its Nintendo's games console for this Generation - not a prototype for a new model for next year. The next Nintendo console will be out in 4-5 years.
Also the DS lite came about due to technology progressing and competition from PSP. The DS Lite rocks compared to the grey brick DS. Nintendo made a mistake with that one! The fact that it is the size of a brick doesn't bother me. Its the goddamn screen brightness that sucked with the old DS. - My old Sony ericcson t610 screen was brighter than the original DS. So there's no excuse for it, you can't play games in the sunlight...
