I'm not sure they even have a plan at this point. As long as they don't do another reboot, that would be insane, and hillarious. It's also possible that one of them will cave and a new deal will be struck.
Which is what I'm really hoping for! I mean, if Disney can backtrack on James Gunn and reinstate him, they can go back to how things were with the Sony deal, right? Obviously a lot more is at stake here, but it was working for them, why fuck it up?!
