Wolverine has always been an incredibly popular character, he was before Jackman ever portrayed him on screen, so you’d think Fox would want to bring him back sooner, rather than later.
Nobody knows what the future holds for the Wolverine character.

Having said that, letting Jackman’s portrayal fade from memory is the best thing they could do to give a new Wolverine a chance, and the longer the wait, the better, as far as that goes.
