I'm glad you included the X-Men and FF teasers, because I wanted the ask what everyone thinks about the timeline of introducing them.
The FF brand is thoroughly damaged that if they just did another movie it would flop, so they'll need to introduce them in another movie as they did with Spiderman, which shouldn't be too difficult. They'll probably want to reboot them asap so at the end of the next Avengers would be a good time to tease them, although they won't be able to really include them until a later movie, I've heard people say Guardians 3 but I don't know that I want the final Guardians film to be a springboard for a new series.
The X-Men on the other hand I feel should be left alone for a little while, give people time to understand that the previous franchise is done for. I don't mean a really long time, just not as soon as Avengers 4 or one of the next few movies.
Do y'all think they're going to build up to Galactus like they did with Thanos? Personally that's what I most would like to see.
It's pretty crazy that just as Marvel is ending this first era so to speak they now have these new characters to work with, should make it really easy to distinguish the movies going forward.
