I'm in the same boat regarding purchases in the near future (recent big orders at both J&R and AllDirect), and also have the J.J. Johnson set on the radar for last chance (along with Parlan and Turrentine).
I'm not so worried about these OJC prices--J&R's sale covered other labels, also, and AllDirect has just brought the OJC prices down a bit to be in line with their other prices, e.g., Blue Notes. However, other indicators--like the disappearance from Fantasy's site of the list of upcoming 20-bit K2's--have me concerned about Concord's intentions. Hopefully, they're just in a holding pattern for the moment and, while deciding what to do about future releases, won't delete any current titles. I don't have the time, knowledge, or money right now to figure out every last OJC I don't have yet that I might want (although I've picked up quite a few in the past few months).
