It hasn't been finished yet. This is a project on the long-term plan, not on the for immediate release list.
We have half the maps, the full plot and a third of the encounters done... but then the writing team conked out on it, so I'm doing the whole thing now.
And with my current schedule, (writing a book for Paradigm Concepts, co-writing a book for MEG, and about to release Son of a Portable Hole Full of Beer* that means delays.)
* Submissions deadline for Son of a Portable Hole is in 2 days...
