This post won't have any spoilars for Avengers: Endgame, because I haven't yet seen it. It probably won't be long either.
So after Avengers: Endgame is over, and after Spider-man: Far From Home, what other movies do we know are coming? They haven't announced much yet, but we know we're getting a Spider-man 3, a second Black Panther movie, Antman 3, Dr. Strange 2, Guardians of the Galaxy Vol.3, Captain Marvel 2, The Eternals, and a standalone Black Widow movie. That's easily enough for Marvel phase 4, although it lacks any of the exciting tie-ins we've come to expect, like The Avengers films and Thor: Ragnarok. They obviously have quite a bit up their sleeves.
In addition, Disney Plus will have a bunch of Marvel television shows. From these, I'm really not sure what to expect. They've named the Black Witch and Vision show “Wandavision”, which honestly just sounds dumb. I hope I'm proven wrong and become a big fan. And for Loki's new show, the description I saw reads that the show will follow the Norse god as he pops up throughout human history as unlikely influencer on historical events.
I'm already tired of it. Lastly, there's going to be a Falcon and Bucky team-up show. I really don't know what to expect.
As for what new stuff I'd like to see from Endgame this weekend? A Fantastic Four intro would be great. Having Pepper become Rescue would be awesome. And Stan Lee's final cameo.
