Chise will pilot Dynadiver
With Gauma gone/become part of Dynarex, Team Dynazenon is one pilot short, and since Goldburn doesn't have a cockpit, Chise is the logical choice to take Gauma's place in piloting his portion of Dynazenon.- Jossed. The second trailer makes it fairly clear that Gauma is a Ghost in the Machine, with Daiki Hamano being credited as "Rex".
- Actually zigzagged, she's piloting inside Dynazenon alongside the others on the final battle, but she is seen alongside Koyomi while happening, so it's unclear whenever she went immediately into Dyna diver right after or not, it seems that Gauma/Rex doesn't need any pilots for his Dyna Dex form, but for his Dynazenon Form he needs the other members of the Team Dynazenon, as he only uses that form when the others join the final battle.
There will be a new live-action Gridman series.
This time with Akane as the protagonist. We will find out what her deal is and what her New Order form exactly is.
