The memo doesn't show any timetable would would make sense that the name change will come with the upcoming Valhalla chip design. The new chip will move the CPU and GPU into a single chip and will have less power consumption as well as well as make the system cooler. Although there is no official timeframe for the release of the Valhalla revision, many believe Q1 2009 is the time when manufacturing will begin.
