Also note some people are playing current-generation Xbox games on the Xbox360 in this video (MX vs. ATV Unleashed and Halo 2), this could mean that, at least in the testing stage, it is backwards-compatible. BBC and nwsource report a Microsoft executive said they hadn't yet determined whether the new Xbox 360 would be backward compatible. Microsoft is aiming for backwards compatibility but is still facing technical difficulties (because of the move from Intel x68 to an IBM PowerPC CPU and from a Nvidia to ATI gfxcard). Analyst Michael Pachter says the situation may come down to whether Microsoft is able to license patented technology from one of the processor vendors for the original Xbox.
