The X-Men have always been my favorite comic book team, so I was looking forward to them coming to the MCU after the Fox sell. Last year, there was a lot of speculation that it was going to happen during this current phase.
It came out a few days ago that Disney had to buy all of the active contracts, so they can't recast until the contracts are up in 2025. That's why Patrick Stewart appeared in MOM and Evan Peters was in Wandavision. (there have been so many fan theories about what those castings mean and it turns out it's just a contract issue.)
Anyway, I thought that was interesting.
