Voted "other" for "none of the above".
While I can see a point in resembling or doing remakes of old Amigas in an FPGA (or even in silicon), most prominently the A500 but perhaps also the A1200 (there might even be a small commercial gift-market for a Clone-A based "Amiga in a Joystick" bundled with a few games), I see no point whatsoever in creating "new" hardware that would be a museum object the moment it was born.
It wouldn't be an Amiga (it would probably even be incompatible to some degree) so it fails in the "Retro Amiga" genre, and it would at the same time be laughably behind in all technological aspects today, so it fails in the "New Amiga" genre as well.
Fail, fail.
Sorry!
