Important to remember that ARM is talking about instruction sets and not cores. There's still a lot of differentiation going on among SoC vendors but the common ISA really helps with the app ecosystem. If you're really serious you don't have to get a core from ARM, you can do your own (like XSCale was) and still benefit from the common ISA. Not sure how expensive that is, though. Anyway, it would be great to have a healthy competitor for ARM but right now it's hard to see what problem that's trying to solve.
