Where is Microsoft going?

All the new game consoles (PlayStation 3, XBOX 360 and Nintendo Revolution) are based on PowerPC processors. And recently Dan Fernandez blogged about the XNA Framework, which allows to develop and execute managed code on both MS Windows and XBOX 360. So theoretically XNA can be development platform for all these game consoles, but that's unlikely because it will make development much easier for the "enemies".

But anyway - here are the facts:

• MS supported PowerPC processors in Windows NT, but dropped the support before release of Windows 2000.
• Both XBOX and XBOX 360 are based on modified Windows 2000 kernel.
• XBOX 360 uses Xenon processor, based on IBM's PowerPC technology.
• CLR for PowerPC (XNA Framework) is ready.

Do you think (as I am) that Windows is going to support PowerPC again? It would be fun, especially, after Apple moved from PowerPC to Intel processors.
