I think the amiga has a better chance of revival when Hyperion accepts that Haage and Partner changed from PPC to X86 and support that too...
Fixed it so it makes sense, but I find that highly unlikely. I have composed a sort of chart outlining the most likely future of the three Amiga-Like OSes:
Current Future
MorphOS PPC------> ARM & PPC (Or X86?)
AROS X86 & PPC--->X86 & X64
AOS 4 PPC---------->PPC
Thats the platform future of the three from looking at the way everything has gone. Of course, I cannot predict the success of each one, but AROS will probably join Linux, BSD and Haiku in the endless struggle against Windows, while MOS and OS4 will probably continue to go head-to-head for a long time, in time the MorphOS team will probably finish out the G4 and G5 line of support and either expand into the OS4 market of machines (As long as Hyperion has money they will find a PPC supplier) or look into ARM more likely than x86 as ARM machines have been proven to be cheaper. But I can't see Hyperion making too much of a profit
