I'd also like to see a Natami or other advanced FPGA type Amiga that brings all the modern conveniences and a bit more more power inside an A1000 case replica, with an Amiga A5000 label on it. It would probably have to ship with classic OS, but long term I might be interested in seeing OS 4.x back ported to it, or likewise AROS 68K might make sense there too, if classic OS is a dead end to continue.
Then in another 3 or 5 years or whatever I'd like to see a refresh using newer more powerful FPGAs that sees an A6000 model brought out, and so on. Meanwhile hopefully both OS and applications have progressed a bit in that time too.
For me I don't see the point in incorporating PPC tech as it doesn't mean much to me in the history of Amiga and seems like a dead end anyway. I've come to terms that we'll probably never see the Amiga OS with proper features like memory protection, SMP, etc., that make it worthwhile running on cutting edge hardware (AROS can try for this anyway it's already on cutting edge hardware). I'd like to see the 68k architecture and the chipset extended and added to as a natural progression, while retaining compatibility with 68k Amiga software. I do realize we'll be 10 to 20 years behind the tech curve but that's OK.
I don't really care who develops or sells it as long as it gets done. If CUSA has some assets and ability to bring hardware, brand, and OS people together great, because nothing much seems to be happening otherwise. I wouldn't be one of the 500 people on a preorder though, I'd only buy this if it was already available and I felt like it that day. But of any Amiga hardware that was to come out, this is what I would buy.
