That side of the Fox/Marvel business is doing just fine thanks to recent films like Deadpool.
Unfortunately, it’s highly unlikely that any agreement like the one Sony made has much chance of taking place regarding the X-Men.
While there might be a slight chance that something could happen with the floundering Fantastic Four, as Fox is unlikely to be making any money off that license for the foreseeable future, there’s little reason for Fox to want to share Wolverine.
It shows just how big, and important, the MCU has become that Hugh Jackman could have reconsidered a major career move like this if that option was open to him.
