It would be really cool if Feige can tweet #Welcome Back Home First Family and Merry Mutants! on the day the deal closes.
But Feige, being the professional he always is, will most likely won't not do that; keeping his twitter feed completely silent on March 20th and beyond. Press for Endgame is when we'll get an official confirmation that they have rights when Feige says something along the lines of, "Yes we now have the rights and we're very excited to finally have access to almost all of our characters and we're thinking about it." But Feige will likely caution people that just because they have the rights that doesn't necessarily mean Marvel will all of sudden prioritize the Mutants and the First Family over the characters they currently have plans to make movies out of. So I expect Feige to give a general statement about how nice it is to have the characters all while tempering fans expectations about how soon will they do anything with those characters.
