pretty safe bet that revision two is already on the drawing board by the time revision one hits the market. That said, it's still somewhat embarrassing for UMID that we already have leaked proof that the M2 is on the way to replace the just-barely-official M1. Judging by a purported roadmap, the MID M2 will be smaller than 3-inches and will boast calling capabilities. Furthermore, it'll support HSPA, WiMAX and a slew of other wireless protocols (or at least some of 'em), but we wouldn't expect to see more of it until late 2009. Unless UMID wants to completely cannibalize sales of that M1, of course.
