Microsoft promised to send out XboX 2 developer's kit sometime in Q1 next year. This kit will finally have an R500 card inside which means that R500 development is quite advanced. Microsoft's current kit is powered with older Radeon 9800 cards and things will get much faster this time round. Developers have to code on Shader Model 3.0 hardware.
We are not sure which one of G5 machines Microsoft wants to send to developers, but yes it will be a Mac G5. It's kind of funny but you have to remember that XboX 2 uses a RISC CPU and is not Intel X64 compliant CPU anymore.
It will be funny to see this G5 machine running some kind of Windows OS.
Microsoft is doing huge things to make this console successful. A Microsoft OS that runs on G5, a change of its graphic partner from Nvidia to ATI and a risk it for a frisket with a RISC CPU.
That's a huge step but you always have to be afraid of Sony and its new marriage of convenience with Nvidia. µ
