The MR9800 (M18) is actually misnamed though, since it's based on the new X800 core rather than the old 9800 desktop chip.
Theoretically, the new ATI PCI-E chip M28 is a PCI-E version of the M18 with a similar (or the same) core. The main advantage will be upgradeability. There have also been rumors of an M28 Pro, which would be a notch above the M18/M28 performance.
