O.k. I just look up on the PK roadmap on trello, and and it shows that the new species (likely gallimimus) is gonna be in update 14, and so their will be no new species in update 15 for now.
Makes more sense like that imo. The art side of development will have its hands full for U15 with ontogeny models and paleobotany, meanwhile U14 was mostly AI stuff before this reshuffle.
