As I understand it, there will still be PCCA blends but they'll be sold under whatever name McClelland wants them sold under. McClelland always blended these for mr Hamlin anyway, he's apparently just getting out of the tobacco selling business. Look for them to be even more readily available as a McClelland standard.
From Hamlins website:
"As of October 25, 2008, all PCCA blends have been "discontinued" with no new blends being released by us. McClelland will be nationalizing PCCA blends so that they are sold under the McClelland label and available nationwide through established retailers. All "rights" to the blends, their names, designs, artwork, etc. have been turned over to McClelland. I believe this will result in the reintroduction of some older PCCA blends not currently in production, but we'll have to see."
