So it might mean, all that processing power they boast will either have to be tweaked to run older games [ATI vs Nvidia], or you'll have to get new versions.
Sony had it easy ... PS2 included the guts of the PS1 on a single chip.
Consumers won't pay for or swap out their old XBox titles for new XBox 360 discs because it would be too much of a hassle and what about non Microsoft games.
There is no financial incentive for a developer/publisher to recode their old titles for Xbox 360 compatability.
Microsoft has to do all the hard work themselves.
Binary "recompilation" has already been used successfully on the Dec Alpha (google for FX!32 ) when you ran NT 4.0 and loaded x86 Windows programs on this non Intel processor.
Intel is using the same technology for the new generation Itanuim processor to run the foreign x86 code.
And Transmeta (Sony Via laptop) with their "code morphing" technology to run x86 code on their foreign processor as well.
I reckon that when the XBox 360 ships it will contain a 'translation/loader'
either in ROM or on a separate disc for the best selling Xbox titles before and using that before inserting your original XBox disc for getting the graphics/movies to be loaded.
The tricky part that most folks not considered is that most XBox games assume a hard drive would be avialable all the time (now optional with Xbox 360).
If they pull it off ... it will be an amazing technical feat.
