Well, depends on your point of view.
Ive wondered why they went with PPC instead of x86.
Ssolie's explaination when it comes to his personal intrest in the OS seems fair enough, if not very efficient.
During the Amiga Technologies days, that idea was considered. The backlash from the community was immediate and vehement. It would not have been a popular choice.
Now, as far as I know, Hyperion only have a license for a PPC port. If they wanted to do an x86 port, they would have to re-negotiate with Amiga, Inc, and I doubt that would be successful.
But if you want to run Amiga OS on x86, you can use WinUAE or run AROS.
