I've never seen PPC as being an important part of the Amiga platform. As far as I'm concerned, it's an architecture that was used in some third party accelerator cards and nothing more. That doesn't mean PPC support is a bad thing or a hindrance in any way, but there's no getting around the fact that x86 is the only viable option for powerful and affordable hardware.
I think having MorphOS and AmigaOS exclusive to PPC has actually worked out for the best. If those operating systems were available for x86, we probably wouldn't have AROS today, and it would be a shame not to have an actively developed FOSS member of the Amiga family.
