I expect them to be there as well. Saving up my gems until then...as much as I like the Vampire theme, I don't think they'll be strong enough to compete with in the current meta; I sure hope Mermails have good support.
We are going off an assumption from the posted Leaked cards on another thread. U.A., Vampire, Inzektor, and Mermails were posted a while back and we just received 2 of the 4. Either an NPC deck will include the other 2 or we just might get them in the next set.
