By now everybody knows Microsoft's next gen console will use an ATI GPU instead of the current NVIDIA powered Xbox. The question on a lot of people's minds was, will there be backwards compatibility? While Sony and Nintendo already announced that its new consoles will be able to play previously released titles, Microsoft was quiet on the matter and only at E3 did we get a vague "best-selling Xbox titles would work on the Xbox 360." 1UP finally got some more information as it seems that Microsoft has bought a technology license from NVIDIA to allow the X360 to emulate using the IBM PowerPC CPU's. Several "patches" will ship on the X360's HD at launch, while and others will be made available through Xbox Live at a later date.
