The problem is that we, Amigans, have already lost the power to bring HW innovations. The times of revolutionary custom chips are over and forgotten. So we had to rely on innovations of others... like we relied on PPC. However we lag so much that meanwhile we adjust to new HW platform, the platform itself is no more new, innovative nor generally supported.
Either we stick to mainstream HW with the hope it remains mainstream in the future so we have enough time to adjust or we bet on some innovation with the risky hope it will become more popular in the future.
What a pity that one of the possible mainstream solution (Amithlon) was killed.
