I was referring too the X5000 which is PowerISA architecture. A1222 is planned to be around $500 which is not all that expensive, X5000 is on the expensive side. Considering my use of such a computer would be to run various audio software that was designed for much slower single core machines I suspect a dual 2ghz processor with XMOS coprocessor would be quite satisfactory. It would allow me to use some software which does not play well with emulators and would probably be just about ideal for my needs when it comes to a studio computer.
I suspect the A1222 project was scrapped due to shutdown fallout, chip shortages, etc but who knows, it may still happen.
