In an interview given to the BoxOffice Magazine, Director Joe Jonhston briefly talked about Jurassic Park 4:
“Well, there is going to be a Jurassic Park IV. And it’s going to be unlike anything you’ve seen. It breaks away from the first three—it’s essentially the beginning of the second Jurassic Park trilogy. It’s going to be done in a completely different way. That’s pretty much all I can tell you. […] If you think of the first three as a trilogy, number four would be the beginning of a second trilogy.”

Good to have a confirmation that there will be Jurassic Park 4, but when does filming start? Hope he will give more details about Jurassic Park 4 soon!
