I tried to find it, but somewhere, someone said if I recall correctly, Primitives IV in about a week after GenCon, which would be any day now...but honestly, I'm guessing another week. Coming back from a convention is very hard work, I'm sure the folks that helped Catalyst (as well as IWM) are still trying to recover.
EDIT - And Adrian posts right before I did! LOL So yeah, 2 more conventions to go to...so don't expect anything ASAP.
