That's great news as it brings the franchise basically full-circle, in a sense. Although expected, it's still a shame that they're not going to even give at least one original lead a cameo. Hopefully they'll at least mention them by name, if not, refer to their experiences in past films as was done for TLW in the JPIII Dr. Gant presentation scene.
Another note, which I find interesting in Trevorrow's response is that Dr. Wu can basically now flourish under new management after John Hammond's loss of InGen. It will be interesting to see how Patel Corp treats their employees, but I hope they still mention something about Dodgson's espionage with Biosyn. Maybe Dodgson tried to contact Wu before hand?
Eh. I'm getting ahead of myself.
Also, here's the rest of the insightful interview....
