according to an MS pressrelease found via theregister here http://www.theregister.com/content/54/33741.html MS has ditched Intell and have gone with IBM for their new XBOX . This probably means a G5 varient, which would mean no compatibility with XBoX1 games. Add this t othe rumers of a Q4 2004 release and I see littel reason to ontinue to get XBoX1 titles.
