I am a huge fan of the MCU, but at this point I kinda wish they had treated Endgame as a full-stop. End of the MCU, all actors released from contracts, etc. Then, start MCU version 2. Skip the origin stories since we all know them by now. Recast the big names (Iron Man, Thor, Cap, etc) and make new movies for those characters and/or new Avengers team-up movies. Integrate the Fantastic Four, Xmen, Moon Knight, Shang Chi, etc into this MCUv2. This would allow us to have the "real" Iron Man, Cap, etc interact with the FF and the Xmen (instead of the probable/eventual "FF meets Iron Heart" or "Xmen meet Shuri" storylines). It would open the door for additional established comic book story lines for the primary Avengers that didn't have a chance to shine in the original MCU.
Alas...
