The trailer also seems like it includes the InGen helicopter from Jurassic Park rather than the one used in Jurassic World. So that might be another skin options for the ranger choppers.
So I'm the only one who is actually hoping for TLW raptors rather than JP3
Although I'm really excited for JP1 animals (missing Dilophosaurus and Gallimimus tho)
TLW raptors are likely another skin for the JP ones, they did use the same models for them in the movie.
With the changes being more than just a reskin, I'm thinking that there's another slot being introduced for the different generations/iterations of InGen dinosaurs. (For the term, iterations is used in the books for their different version numbers, and with Ludia's JW Alive they use Generation for the different looks), or they reuse the one that is currently only used to give the Indominus it's camo ability...which would still be nice to see put on the Carnotaurus and Velociraptor since those both had it in the books.
That would allow the legacy skins to be put on the older models and the reverse to add more variety to several of the dinosaurs that have large numbers of them in a pen.
