Joshua Jackson also believes that Fringe will be revived in some form.
We also reported in March that producer Jeff Pinkner has plans for an elaborate comic book series. Producer J.H. Wyman also revealed at the panel that Season 5 will pick up where Episode 4.19: Letters of Transit left off. The episode is set in the year 2036, foreshadowing a world where the Observers have taken over.
The show also played a five-minute video for the fans, showing scenes from Season 4 and Season 5, with main cast members coming out of an "amber" state to do battle with the Observers. That video isn't available yet, but we will share it as soon as it comes online.
