Jurassic World will undoubtedly be one of the most interesting franchise reboots of 2015. However, just like the other films in that boat, Star Wars, Terminator, etc., we don't know very much about how the studio plans to revitalize the series.
The last Jurassic Park hit theaters in 2001, meaning that the upcoming entry is unlikely to be a direct sequel. That basically leaves a reboot, a remake, or a mostly standalone film set in the same universe.
Director Colin Trevorrow shed some light on the story, hinting at the latter option.
A fan on Twitter asked him if Jurassic World would be a reboot. While he didn't completely debunk that idea, he did state that the film would be set 22 years after the events of Jurassic Park, more or less placing the film in real-time.
@pfcbains916 Reboot is a strong word. This is a new sci-fi terror adventure set 22 years after the horrific events of Jurassic Park.

That seems to indicate that while the film will be set in the same world as the previous three, it won't necessarily star the same characters. We'll hopefully know more once the project heads into production next year.
Jurassic World is aiming for a summer 2015 release.
