Truth is without a proper buisness-plan (including lots of funding) an ARM-port makes just as much sense as a x86-port. And once such a port would be done you'd still be lacking any decent SW since some stupp isn't portable for various reasons.
Another point is, while you ditch the 68k-legacy-support, why not completly overhaul the APIs to modern standards ?
And if you do that anyway, why nor reuse existing (open-source) libraries ? -> YALD ...
Or in other words, why would anybody (Genesi) use MorphOS, RiscOS or anyother ObscureOS on an ARM-netbook when "normal" OSes provide so much more. Unless you can present that in a convincing form to the MorphOS-team all talk about an ARM-port is futile.
