Im not sure how much it will sell but the 360 is no xbox. Its selling more games by far, it has far better 3rd party support, microsoft is actually trying in Japan (yes it isn't working but the userbase for the 360 is still better then the original xbox), the price is still expensive and can be dropped significantly (in comparison the xbox was a lot cheaper at this point in time) and finally microsoft wont have to cut the 360's life short like they had to with the original xbox.
