MacCentral has posted a mini-preview of Myth III that mostly constitutes quotes from Nate Birkholz. Here's a segment from the preview:

Users have noted that the problems mentioned by MacSoft in its status updates have been confined to Mac OS X -- given that's the case, why not release the OS 9 version now and offer Mac OS X users a patch or upgrade later?

We just don't want to divert the resources we have to get this game out to change the application to make it a Mac OS 9-only app, said Birkholz. I'm not sure what sort of engineering that would take, either.

In any case, it shouldn't be too much longer before Myth III is released for Mac OS 9 and X. (Thanks Myth Village)
