I believe the attractive way forward for RISC OS, would be for it to remain running on its own native hardware. The Iyonix path continued, so to speak. However, it is apparent it's becoming increasingly difficult to sustain ongoing development, with the current state of market in mind.
To keep costs down, profit from PC's hardware, and keep alive some of those lovely software titles, emulation is a viable solution.
If you look outside the cosy RO market, you'll find technology development is happening at a furious pace out there. From a technical perspective, our native hardware (and software, partially because of it) is seriously behind now in almost all aspects. People are leaving the platform market not just because of the OS fork, infighting, dubious behaviour of ROL, Castle offering RO for sale, lack of various types of software development - but also simply because they feel they get a better overall deal when running Linux, Windows or Mac OS X, never mind the glorious benefits of the RO GUI. Our market has become extremely small, perhaps too small, to justify commercial product developments - both in hardware and software.
The A9home and Iyonix were not developed on their own. They are side-benefits of more economically profitable developments. Just look at their Advantage Six / Pace origins. IMO they were adapted for desktop use in our humble market. That is completely understandable - it simply wasn't worth it otherwise! What I mean is that some people are still living in a substitute Acorn dream, whereas the reality is that almost nothing is left from that era. All that is left is the wonderful, but seriously handicapped, RISC OS system. How many people do you know who don't run a PC or Mac alongside their RO machine? Well, I know one ... me.
