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.

I love that second one. Richard Attenborough was a great actor in my opinion, at least for JP.

Needless to say, I'm pretty interested in this movie. Gonna have to keep an eye on it.
