How can they recognise them as the new copyright holders before they're the new copyright holders?

Honestly, where is the notion that they want to sit on it even coming from? Is there any indication that they've been so unhappy they'd rather nuke the entire IP from orbit than cut a deal? The wording of the complaint is about all we've got, and that talks heavily of negotiating a new license agreement. Everyone's acting like it's the most likely outcome of them getting the copyright, but nobody has any reason to believe that outside of projection or paranoia.
Does anyone think Fox or Disney would renegotiate if they didn't have to? This is the legal recourse to get a renegotiation that levels the playing field. There's really not much other benefit to it.
Taken at face value, the only thing that seems to suggest a risk is Fox/Disney not wanting to pay any extra, not the Brothers taking their toys away and leaving the playground. If they do decide to do that I really wouldn't be surprised if it's because Disney/Fox tried to screw them, not because that was their master plan.
