I must say after visiting the forums at
www.natami.net my impressions of the project team went up significantly. Gunnar von Boehn seems to have a very thorough understanding of what needs doing and the advantages/disadvantages to various approaches to an issue.
They are developing what I would probably call an Amiga 5000. This is what you might expect to come out of C= after the A4000. This includes better graphics (including rudimentary 3D support), better sound, better CPU, improved system throughput, built-in scan doubler, etc...
The best part is that in the long run this functionality sounds like it will be condensed down to not a lot of chips - similar to the Minimig but not quite that simple.
My hat's off to these folks - if they can see it through it will be a kick-ass system. The next-gen things they are discussing, such as a custom N68070 CPU (next-generation 68040/68060) and possible SIMD extensions sound quite interesting.
More power to them.
