One of the things Jackman's return, says to me , is that there may indeed be some meat behind the report that they Marvel Studios won't be able to recast the role's until the Fox contracts run out.
I could see Feige and Marvel not wanting to sit on such valuable ips and characters such as Wolverine, for several years before exploiting them.
We, the audience, would basically have to wait until the middle ,to the end of the decade, before we would see a character like Wolverine if they were to wait to recast.
So , I could see Feige and Marvel / Disney , feeling that it's worth it to bring back some characters/ actors like Jackman's Wolverine, and then eventually ,casting 616 versions them after the
Secret Wars, multiverse storylines.
That may not be what alot of fans are hoping for, but that's what I think could happen.
But just I'm spit balling and not saying it's a certainty .
