Aros is already supporting ARM... and AmigaOS will propably never be ported to other platforms because of licensing issues
Not according to Hyperion, who posted in June, 2011:
Then there are some legal issues like some licences being tied to PPC only.
All of this could be worked around however given sufficient funding. E.g. an ARM/X-Scale version of AmigaOS 4.x is perfectly possible.
