Since all these "ifs" are just "ifs", and given Amiga Inc's previous track record, the best bet IMHO would be for Amiga Inc to call it quits, and open source the Amiga IP (both software and hardware), therefore giving it to a group that cares, e.g. the community, to do something that's actually useful.
Otherwise, there will just be more announcements about yet more overpriced and underspecced motherboards running an old fashioned overpriced OS that just happens to have an "Amiga" name on it.
As for the dead horses, well, this subject has been discussed just a few times!
Realistically, A.Inc will do nothing, as before, and AROS will be the only hope.
Just my 2c!
