I believe they are waiting on when the stories actually start to converge. At least I think that they know all the Marvel TV series are connected to each other to an extent but they are just focused on The Defenders Saga. I assume when we get AoS characters back, they will add the ABC series.

They had no problem on adding AoS to the Nick Fury collection when SI was about to be released. Marvel.com Nick Fury article also includes AoS info. And the ABC series are currently under the "Agents and Inhumans" group so I think Marvel knows they belong together. At some point they will add them to the timeline.

Also unlike the Defenders Saga, some of AoS Season events happens between multiple Movies. They would have to split it up by Episode by Episode instead of Season by Season.

It is finally happening. YES!

They are still leaving out Agents of SHIELD, Agent Carter, Runaways, Cloak & Dagger, and Helstrom

Agent Carter has been put under the MCU category on Disney+. It has not been added to the timeline but it seems Marvel Studios is finally ready to put down the barrier between what they created and what Marvel TV created eventually and fully.

Since Runaways was removed from Disney+, I doubt we'll get the full timeline. Well, we can't have everything in this life. I also wish they would add Agents of Shield: Slingshot to Disney+.

The Sad Thing is that Agent Carter is probably the simplest one to put in the timeline and you don't even need to split it up unlike AoS, Just put it before Captain Marvel and After First Avenger, it's not that hard Disney lol.

Also I really hope that's just in a random order and not how Disney+ wants you to watch it.

I'm wonder if runaways will return to disney plus ?

My Disney Plus has been updated to include the MCU complete timeline but doesn’t have the seasons split. Is this something still coming to did they only include the split seasons on Marvel.com.

For those saying AOS is hard to add I think it would be easy enough to add them. Just don’t split the seasons but rather just place the seasons where they start on the timeline. That being said I’m doubtful they would ever want to add AOS S6 + S7 to the timeline between Infinity War and Endgame due to them basically ignoring those movies. If they ever add the show to the timeline I’d imagine they just place the whole show after The Avengers.

Literally no reason they can’t include Agent Carter though that’s any easy placement.

Its strange that The Punisher S2 and Jessica Jones S3 are placed before Ant-Man and the Wasp. Also Loki S2 being specifically after The Marvels is strange too.
