Jurassic World!

There is a confirmed cameo, technically 2.

 Spoiler

Dr. Henry Wu, the geneticist from the first film, he's the one who created the new hybrid.
also there is a statue of John Hammond in the film, so it counts as a cameo and a nice little homage since the actor is dead

I do hope there are more though, but it doesn't seem likely

And yeah, i'm glad it's a soft-reboot too. Starting over and using the original films as a base is a good move, especially since it's a franchise pretty much filled with hype and nostalgia. If they started afresh it would just be another monster movie.

I also find it funny that the third film has been completely ignored, lore wise. As far as the movie is concerned, it's a sequel to the second film.

Not exactly, there are supposed to be some "quarantine zones" in both the island and the world, in which dinosaurs migrated and made it their homes, which is basically a left over of JP3. I would love to see the Spinosaurus again though, such a badass dino.

Also, the fact that they mention that the new company is atm fully invested in Ice Age mammals and animals makes me think the studio might be planning on spin-off movies.
