Microsoft has revved the official Xbox site, adding flashy new graphics, the impressive demos that had debuted at the March announcement, and a movie highlighting various industry moguls' comments on the next-generation console. Most interesting, however, is the new specs comparison page that lists the Xbox's as 733MHz, a jump up from the 600MHz announced in March. This would appear to be a minor change in the right direction, yet it serves as just another reminder that specs can very well change in the year and a half leading up to the Xbox's launch.
