From what ive heard, the Dual Core AMDs who in fact are doing the multi core design for the Xbox 2, will be ready q1 05 for the server and workstation market, and by Q2 - Q3 the desktop versions will be ready and also i do hear taht the R520 is slated for mid 2005 release as well as the NV50, so i cant see the Xbox 2 being delayed into 2006, it would probably only come out a few months after AMD and ATi release their PC versions.
IBM is making the CPUs for the XBox2, not AMD (and considering you don't even have this straight, I find your information highly suspect to say the least). It's supposedly using a dual-core variant of the Power5 (yes, using the PowerPC instruction set), which is not looking to be widely available until at least Q1 '05. I wouldn't expect the XBox2 until Q3 at least, unless IBM changes their tune. And unless MS is a *lot* further along than they're letting on (and they have a lot of people under NDA), they wouldn't have any games if they launched it much earlier than that.
I wouldn't be shocked if ATI had the R500/520/whatever out in late 2005, but I just can't see them pushing a totally new hardware rev before Q4, unless they've decided to just abandon the R400 architecture as rapidly as possible.
But, seriously, there's no way to predict the market or the new products with much accuracy this far ahead. That said, I doubt anything will seriously challenge the 6800GT for at least a year -- assuming the fall/winter refresh parts are similar to the 5950U and 9800XT in the last generation (ie, just clockspeed bumps).
