No more details, as they would reveal the ideas (both marketing and technology-wise). They're simple and easy to copy, therefore "saying nothing" is the safest thing to do for me.
Yes, I know about Natami and FPGAarcade, but I neither want to create a new platform (like Natami does), nor do I want to address the existing Amiga people only.
Those two projects are creating a nieche within a nieche with sales prospects of maybe 200 units total. Clone-A goes into the other direction, where it can please Amiga-freaks, but also attract new customers and new developers - and the latter is what we desperately need.
