Lately I noticed a pattern with specific DLCs, Return to Jurassic Park and Camp Cretaceous. We get seven dinosaur skin variants for established ones and two new dinosaurs in each.
I believe the Dominion DLC will turn around the amount we'll get since we have so many new dinosaurs coming in the movie and a couple new skin variants.
I know we'll definitely get Therizinosaurus, Quetzalcoatlus, Atrociraptor, Pyroraptor, and Giganotosaurus because they have a huge importance in the movie. I'm sure we'll get Dimetrodon which would be exciting, and I would love to see Microceratus in the game as well, its new design looks more realized and could fit into the world.
I'm not sure about skin variants for T-Rex and Iguanodon. Dreadnoughtus looks cool in the movie and I would love to use that look more than the game's version. It's not bad, but I don't use it much. Also, I'm not sure about the addition of Oviraptor and Moros. Now I love the oviraptor and would be perfect, the problem is not the look, but more about what it would eat. Its diet is still debated to this day. I don't see them adding egg feeders. Sure, some ornithomimids have been depicted as egg eaters, but it's not their preferred diet. Lystrosaurus is rather debatable as well. I'm just rather debating about would one early reptile or two be enough, but who knows.
There's so much the animators could be doing now for the DLC and it could be overwhelming in doing every single creature in the movie.
