Via SFSignal , J Allard (XBox develpoment chief) insisted that his developers read Snowcrash, to try and provide some inspiration.
In fact Allard is ambitiously going for the Metaverse,
"The Xbox 360's project code-name was Xenon, and an expansive 147-page Allard-authored primer called the "Book of Xenon," based heavily on the virtual world notions set out in Snow Crash, spells out the guidelines of that project."
I'm somewhat sceptical that a games console will get there anytime soon, consoles have too muc of that arcade heritage in their attitude. However MMOG's such as Second Life seem to be heading in the right(/) direction.
