Oliver Wagner said that on his .plan:

The fact that we are supporting MorphOS NOW isn't anything exclusive. Be rest assured that if AmigaOS 4 reaches a state of usability, has a devkit and everything that we'll happily take a look, and possibly port over. The same is true with other interesting developments. There's now a project which involves a "classic" m68k emulation running on x86 PC machines which has reached a state of usability -- it has the means of running "integrated" x86 assembler code, and I've been discussing the possibility of either compiling V completely for x86, or at least offload some of the more time-criticial things notably, the image decoders)to native x86 code."

This raises one potential concern which alot of people who have been against this aspect of the Amithlon will find only further goes to support their beliefs.
The x86 version (currently) looks most likely that it may get support over OS 4.x (and 3.x), only supporting the arguement that the more authors who directly support the Amithlon will lead to the demise of Amiga's/AmigaOS's future path and viability and kill off almost all commercial developers (especially game/app developers) in the process. And furthered even more by developers who also stop directly supporting Amiga PPC Exe's, and split the market further by only supporting MorphOS over AmigaOS.
