Hopefully they will keep the X-Men universe separate. Preferably entirely separate but at the most just have Scarlet Witch cross over because of Magneto and all. And I refuse to accept that she's no longer a mutant and not Magneto's daughter MCU can easily transition her to being a mutant in that Loki's staff awakened her and her brother's powers and they were the only ones that could survive the process was exactly because they're mutants.
