If AMD didn't introduce x86-64, we'd all be using PowerPC and 32bit x86 still. IA64 suffers from the same problems as all the other RISCs out there that died, it has potential to do magic but there just aren't that many magic compilers and the output tends to look sort of mundane.
The whole RISC vs. CISC is off the point, that was decided a long while ago. x86 "CISC" which is quite a bit more RISCy than say VAX or 370 happens to be a very compelling blend.
ARM does have an interesting position in the ultra lower power field though. I suspect that has more to do with ARM being designed for that from the start than the instruction set though.
