Prediction: this will feature Majors in a capacity reduced by post-production editing and fill in reshoots with a new actor as the most dominant Kang variant who will carry through to the Phase 5 projects.
Or they use the series to do some kind of timeline restart that among other things changes the face of Kang. They could also use this to erase some inconsistencies between the Netflix series like Daredevil, the ABC series like Agents of SHIELD and the mainline MCU. I also wonder if the "timestepping" is inspired by or even related to the glitching in Into/Across the Spiderverse, it looks remarkably similar.
Oooh...it does resemble glitching. I didn't think of that. Would make sense though, to bring together all of these ideas of how traveling the multiverse works.
Now that I did catch. Between that and a certain cameo that I can't figure out how to mark as a spoiler (lol), it's clear they're linking the two storylines.
That wouldn't surprise me at all. This was the last project that they had in the can with him. Once it's out they can make some structural changes and quietly drop him
