I promised, didn't I?
On the Myst Forums, from Chogon (Mark DeForest, CTO of Cyan):
This is a small project that probably a very few of you know about. We are porting Myst to the iPhone. Ok, before some of you start groaning, this is an outside funded project that is keeping a few developers employed... but it is really more than that. It is an interesting and fun project. This is also a very small team with three of us (which includes Derek, Rand (not Randy) [Miller] and myself).
The groaning, I assume, is because of the Nintendo DS port of Myst, which debuted a few months ago to an avalanche of held noses. (Someone was passing it around at the Myst fan convention I mentioned a couple of weeks ago. I didn't get a close look, but the disgust oozing from that side of the room was tangible.)
So hopefully iMyst will be smoother.
Other bits from that post:
MORE - UruLive: The current focus is to get the servers back online and subscribers back in the game (in other words, launched!) before the end of the year. [...]
Other projects: We do have a number of other projects that are suspended waiting for publisher approval or other outside funding. These range from a large epic multi-console game to smaller single console games with a number inbetween. All of the games are unique, artistic and have different aspects of exploration... and I can't tell you anything about them until they become active.
