I think at some point Poseidon/Neptune absolutely has to appear in some form. I mean out of the main 7, he is pretty much the only one that hasn't had some interaction with his child. I mean even Athena/Minerva talked to Annabeth in The Mark of Athena and Athena aided Annabeth in that HoO/TKC crossover. Mars appeared before Frank multiple times, as well as Pluto appearing to Hazel, and Aphrodite appearing to Piper. Zeus/Jupiter has been mentioned a lot and even aided Jason in his fight by sending down a lightning bolt to split the mountain. Hephaestus also appeared to Leo in a dream. Poseidon/Neptune gets a mention here and there, but honestly it seems like he isn't being mentioned for a reason.

Also, I think Rick Riordan has built up too many plot points and I honestly fear that things will go by too fast, leaving us a little disappointed in the end.
