Kudos to Total Codex of the Ministry of Security for spotting a post by Nate Birkholz in the MWA forum that further details the release of the Mac version of Myth III. Birkholz writes:
1) On the 17th of November, we said SoonTM. People were unsatisfied with SoonTM and asked for a date, so I went out on a limb and was more explicit, that the ship date, *if it went gold that particular week,* would be in early December. We didn't know if it would go gold that week, or this week, or next week, since no one can be sure how long it takes to fix a bug (without a time machine becoming involved somehow). But since people wanted to know, and were tired of SoonTM , I told them what we were looking at for a possible date. That date changes as the situation changes.2) I didn't mean ...we won't be expecting the gold version of the game for two more weeks at least, I meant we won't get it onto store shelves until two to three weeks after gold date. Precisely, I said, ...we are looking at somewhere between two and three weeks from Gold date. Two to three weeks **FROM** gold date not **TO** gold date. (That's an important preposition.)
This, of course, is why game companies say, SoonTM instead of giving dates.
So in answer to your question, it's coming SoonTM!
If the Mac version of Myth III is intended to hit the shelves before Christmas, it would have to go gold within about a week from today. Can they do it?
