xbox 2 specs leaked

this is from play magazine

Microsoft is not happy. After convincing schematics with detailed information on the innards of the next xbox, still being called xenon, were leaked, the company released a n emphatic statement debunking the authenticity of the report. If however, the rumors are true, the new hardware will be powered by a 3.5+ GHz IBM PowerPC processor and a 500+MHz ATI graphics processor all surrounded by 256MB of RAM. There's also speculation that the controller wil see the deletion of the white and black buttons and the addition of two shoulder buttons

i'd think if they were going that powerful they'd use 512MB of RAM, but if theses specs are true it's gonna be a sweet machine
