from what i read in a magazine i don't remember which 1 at the moment but it said Microsoft will be putting out a new console system about every 6 years compared tosony PlayStation and Nintendo every 8 years. reason for this is to keep up with the latest tech in the gaming world plus to out sell Sony and Nintendo. from what i understand why the x-box 360 is out selling the Sony PlayStation. i don't need to mention why Nintendo outselling both, because that's obvious.
