Who do you think will return for Jurassic park 4?

Y'know, I'd love to see where Billy ended up. I know Tim's Actor still does some parts, But they're more action movies now, He'd been interesting to see, So would Lex. 

We haven't heard Directly from Laura Dern... She Could make an Appearance.

Rexy was bound to return regardless, I don't see why it's such a secret, So It should probably be someone (or) something else. 

Keep in mind, We did see a raptor on the Wrecked Tour jeep in the Posters. 

Perhaps maybe the Big one was tougher then we thought.

Human characters would be better though.

Maybe John hammonds Memoirs are Directly Referenced in it?

Idk, But I can't wait to find out what or who it is.

The only two humans I can see making a comeback are Ian Malcolm (due to the picture of his book God Creates Dinosaurs being a possible cameo in the movie) and Dr. Harding.

The only two dinosaurs (besides Rexy) I see making a possible comeback are the raptor that got locked in the freezer and the dilophosaurus due to the Dilophosaurus Ambush Lego set for JW.

DR. JONES - I would very much enjoy seeing Dr. Harding return to the scene as the park's head animal caretaker! That would be quite neat! Oh, and, yes; it is very dangerous out there - the SPAZ will come in quite handy! ;)
