Yes, Darkest Africa, Gothic Horror, and Gangsters are all pretty much a solid bet for later this year, beginning of 2012. I think they'll come in that order too.
OG/Blue Moon just needs to finish their ACW and NAP ranges before beginning these new ones.
Look for the Gothic Horror to be a "shot for shot" re-make of the old 28mm West Wind line. Which to me is a very good thing!
