You are right about the limited release to meet the FDA criteria. This tactic was used for a number of blends that we got at Morley's several months ago. Likewise for a huge number of SToP and RussO blends, as well as Lane and its cigar brands. As well, the retro Drucquers must have enjoyed the same treatment, although I personally didn't catch up with those till SP put them on their website.
JimI's review is quite descriptive.
