At least its been said already several times that MOS on Mac would be planned. And since the big gap in price between Macs and Pegasos, I don't see any risk for Genesi to do so. I rather see several people interested in MacOS who'll choose the cheaper Pegasos instead of Apple's hardware once it has been adapted by someone for it (or right now already using MOL).
Regarding the Eclipsis: of course it isn't here yet, but that there's no (PPC-based) Amiga-notebook-solution right now has been certainly clear to the original poster.
