investing 200k like trevor confirms (and i think with production, supply and service it well be more) one could likely have designed fpga, hybrid/fpga (as jens suggested) or even an asic 68k system that could otherwise match few hundred mhz machines and be cheap enough to popularize whats left of amiga among retro-fans and geeks. if aeon systems arent having another target audience that may keep them afloat, i dont see gains in such a system in perspective. promarly it was waste of time to relay on os4 development, rather than that supporting big picture, tht means lowest possible common denominator as 68k and such may have effectively attarct more skilled people across the whole community, as can be exemplary seen in mos, os4 and aros community where people are still interested in, say, fpgaarcade.
