Since the dinosaurs are now free, I really want to see something kind of like WWZ (The novel) or something almost like it (Like many apocalyptic movies, but less chaotic). Dinosaurs roaming across the US, or even began spreading across Canada and Latin America. The Mosasaurus terrorizing the Pacific Ocean or the Carribean, causing disturbance to the maritime trade and killing marine mammals or large sharks. The pterodactylus could be capable to fly from the Americas to place like Cuba or, if they could somehow survive cold weather, to Siberia, so I guess they would be pretty dangerous.
The compies could easily spread across the world through ships. Dinosaurs that were bought during the auction in the last movie would simply be exploited. I kind of like to see the return of JW3 spinosaurus, but not sure how it could work. I also think that the T-rex is going to die, maybe by the spino or someone else.
