Obsidian Entertainment to Finally Reveal Cain/Boyarsky Project?

I'm not sure if it'll be the Tim Cain- and Leonard Boyarksy-developed "super secret" project we've been speculating about and even chatted up Feargus Urquhart about earlier this year, but it's certainly worth mentioning that the veteran CRPG developer has taken to Twitter to tease that another game announcement is coming soon. If it is the "super secret" project, we know it's not Fallout and that it's an RPG, but that's about it. Fantasy? Sci-fi? Steampunk? Or maybe even a Vampire: The Masquerade CRPG? The sky's the limit, and I'm excited.
