The last mention was that it is still progressing but is bouncing between authors.
Personally I hope they don't do a word for word copy. There was a lot in the original adventures that could be expanded, and updated with what we now know about the setting.
The third adventure definitely needs the most work, I thought the original was, to coin a phrase, a bit meh...
in comparison with the first two.
I'd be tempted to go kickstarter next year and offer side adventures and supplementary material, it would be nice to have a campaign where the characters reach the end and have to go, ok what's the next job...
