It would be interesting to see if Microsoft picks the next version of the PPC970 (90nm) or a next gen or modified version of the 750 series. In either case, the processor is likely to have AltiVec capability (if any licensing issues concerning Apple/Motorola are taken care of) which will make AltiVec the de-facto standard vector processing technology for future 3D games.
The 440 is an embedded processor, the 750 (as everyone probably knows) is a G3. 440s go into stuff like cars, while 750s go into computers (and some more complex embedded devices)
Nintendo Game Cube uses NEITHER. It uses a processor that was designed especially for Nintento, but it uses the PowerPC ISA. It's called the Gecko.
I'd be shocked if Microsoft used a 970. It's too powerful for a gaming system, especially one that runs on TVs and has to cost a reasonable ammount. Even HD TV runs at lower resolutions than any decent PC monitor.
So, assuming this story is essentially true, that leaves us with really two (maybe 3) possibilities...
1- IBM is going to whip up some PowerPC based CPU for MS like the did with the Gecko (for Nintendo). It's going to be small and cheap, but it will be designed for running a stripped down 'OS' and games.
1a- "son of point 1" .. They would get the latest G3s or the lowest, bottom of the barrel, slowest 970s, though I doubt we'd see a 58 million transistor processor in a $300 game box yet.
2- IBM is going to make some processor for the xbox2 but it won't be the primary CPU. It could be some co-processor or AISC.
Personally, I only saw one good argument for moving away from x86 in the xbox2.. that was the possibility that MS want's to make this NOT be a typical x86 PC so it's harder to run popular OSes on.
This seems unlikely since moving away from x86 would mean:
- porting the current xbox OS (and the future one) to a different architecture
- porting the development enviorment
- breaking all xbox games (or making them run dog slow in emulation, yes emulation is dog slow)
- supporting Yet Another Architecture
- not benefiting from the volumes and agressive pricing available from Intel or AMD.
... the list could go on and on.
Here's my take..
The next xbox uses a P4 celeron or a Duron/AthlonXP. Either are more than fast enough for a stripped down console, significantly faster than xbox1.
If the story is true, IBM will have some silicon in it, but who knows what it will do.

IBM did make X86 processors. They fabbed Cyrix X86 processors. AMD is working out of IBM fabs now too. Maybe the article was slightly off... maybe IBM will be fabbing an x86 processor that will be used in the xBox because the vendor [AMD??] doesn't think they could handle the additional volume??
Hmn.
