The kick off of the 20th Century Fox panel was all about X-Men: Apocalypse, but not before Wolverine himself came out and said a few words. Previous to the panel starting I’m to believe that there was some footage of X-Men throughout the years, so when Hugh Jackman talks about being old that’s what he’s referring to. He then followed up by saying
I have three words for you, Old Man Logan
This statement can be interpreted anyway you want it, and he even encouraged the audience to do so. What I believe he was saying that he has gotten older, so Logan has also showed some age. The third and final Wolverine movie that he’ll be part of, is coming out after X-Men: Apocalypse so we’ll see if he lets his hair go grey. We saw at the end of X-Men: Days of Future Past that he was letting his sides go grey, so an older Wolverine isn’t out of the question.
Jackman has said in the past that he would love to have one more go with Deadpool, and with his movie coming out next year some crossover could happen.
