You clearly never read the Creative Director Michael Brookes Interview
A quote:
"Potentially, there’s post-release content or updates?
Michael Brookes: I cannot comment on that at the moment, I’m afraid. But yes, we’ve got the Fallen Kingdom release in mind, so those things to tie-in with that."
Now tell me, do you really think they are going to let a opportunity for a fully filled Fallen Kingdom dlc slide, and only give us a Indoraptor?
A vague statement that doesnt imply that it might release alot of content. Aka a multitude of dinosaurs. I keep my expectations low and i expect only the Indoraptor. You and the others are very much welcome to either get what you want or have hyped yourself up so much that you get dissapointed and will complain.
