ARM anounced the new ARM series, i cant remeber the number but even if i did mention it you would be confused (1 to 5 are familylies/archetectures while 7 onwards are implmentations that are complient with the faimalies/archetectures)
they say that on a 90nm process it can clock as fast as the fastest intel pxa270's (624mhz) and when more people are using/move to 45nm we should se another speed jump/power saving
that said intel looks to be one of the first out the door with 45nm and plans for pda chips that go up to and exceed 1ghz, however they will supposedly only be 25 percent more powerfull
could be intresting to see how it all goes, espessially considering the arm11 series supports multiple processors
