As for Amiga, Inc. itself trying to rally game developers to code for AmigaOS, the company is kind of at cross purposes on this issue, with both the proprietary AmigaOS (loosely defined, with Hyperion actually in charge at this stage) and the cross-platform AmigaAnywhere as products. In view of the fact that the potential AmigaAnywhere market is many orders of magnitude larger than the AOS market, I imagine Amiga, Inc. will continue to put its efforts into getting games and other apps written for AmigaAnywhere. If and when AmigaDE/Anywhere merges into or is hosted by AOS, then the Amiga platform will get these games, too. But I don't see how it'd be in Amiga's best interests to push for AmigaOS content ahead of AmigaAnywhere.
Really, the Amiga platform would have brighter prospects if Amiga, Inc. itself wasn't fielding a competitor in the form of AmigaAnywhere. I know we like to think of AmigaAnywhere eventually bringing content to the proprietary platform, but the other side of the coin is that people wanting that content can just enjoy it on their current (non-Amiga) platforms; and developers who do hear the Amiga appeal can write for the largest possible audience by targetting AmigaAnywhere.
Any apps (including games) written for the AmigaOS platform will be labors of love, in my opinion, not commercially motivated endeavors. Of course, given the sales record of AmigaAnywhere content so far, the Amiga platform may indeed turn out to be the richest market for Amiga, Inc., which is sad indeed.
