They usually ship in batches. The delay for the P10s has been so long they might send a separate shipment of just those. That's the funny thing about CZ models. Either everyone has one or you can't find one anywhere. There seems to be no rhyme or reason to how they are shipped.
I didn't even think to check Facebook before you said something. They had a post from Feb. 15, 2017 that said this:
Yesterday we received word that our parent company, CZUB, has experienced further delays in the production of the P-10 C. Since SHOT Show, our ETA on the first shipment has been bumped back every few days. Discussions with the factory revealed that the realistic date for first delivery is in late April. We apologize for the delay, we truly expected to begin delivery in January.
