So, it turns out this probably won't be the "final version" after all.
Cyril and I are taking stock of the various species we've done that haven't had FFG write-ups yet, and reviewing them based upon our increased familiarity with the system and in light of some of the rather innovative takes in the official species, particularly in the wake of Enter the Unknown and Suns of Fortune.
There's no time-table on when this "updated" version will occur; much like Duke Nukem Forever, it'll be finished when it's finished. Though hopefully it won't be several years from now.
I've already added a few more species to the document, and Cyril's got a few more he's looking to include as well.
I'm undecided at the moment about what to do with some of the older species that we did that have gotten official versions. I might just exclude them, or we might keep them in as a sort of "historical archive" and "alternate selections" for those GMs/players that are less than enthused with the official versions.
