Well, given that Tony and Nat ( and Vision) are dead, Cap is living in the past literally, Thor is off in outer space and Clint looks like he has retired to the farm and Hulk was badly injured by the gauntlet the original 6 Avengers have pretty much disbanded.
Actually, after Civil War the Avengers were pretty much finished. Tony actually says that to Bruce in Infinity War - "we broke up" I think or something like that.
We still have Rhodes, Falcon and Wanda who might remain as Avengers, but they'll need a new base.
Ant-Man is a quasi Avenger I guess, the Wasp who knows ?
Dr Strange, Black Panther and Spidey are pretty much solo acts and GOTG are their own team.
As such any Avengers will need to be assembled as a new team ( maybe Wanda, Falcon/Captain America, Captain Marvel and a few others).
So it may be a while before we get any new Avengers, and if we don't then Endgame was the perfect send off IMO.
Eh... I doubt that the team is disbanded anymore than it gets "disbanded" anytime any of these all star type teams get a line up shuffle in the comics.
Again... No one said that the team was done and even after the battle there were still things going on where the team was acting as... A team.
And as I stated... Between Black Panther and Pepper Potts I doubt the team will want for money and resources. A need for a new HQ does not in any way mean a group is disbanded. The U.N. existed as an organized body long before the U.N. building was completed.
While I don't think that Dr. Strange can fit Avengering (Avenging? ) into his regular duties I don't quite buy the rationales for the others.
Wanda can for sure still be an Avenger and I think we'll see the return of Vision. Getting a solo series isn't some instant card for not being on a team. If that were the case Wolverine wouldn't have been on like four or five separate teams all at once on top of having his own book.
Sam I think is for sure still on the team. Bucky? Maybe, maybe not, but he's no more morally compromised than Black Widow was.
War Machine? Yeah, why would he quit now? He's the type to carry one to continue the legacy of his good friend.
Ant-man and Wasp are DEFINITELY Avengers now... As they always should have been.
Black Panther is likely not on the active roster and will continue as monarch... But he's gonna be connected to the team in some way. Certainly in the reserve status.
Spidey got knighted. I think he's in the reserves as well and by the time the next film hits he's gonna be "of age". They could put him on full time.
Captain Marvel is for sure an Avenger now.
Bruce is I think still an Avenger.
That's a possible active duty line up of:
1. Capt. America (Assuming Sam is allowed to take up the legacy, which is what that series on Disney+ will likely be about since it's not named Capt. America and Winter Soldier, but FALCON and Winter Soldier).
2. Prof. Hulk
3. Capt. Marvel
4. Scarlet Witch
5. Vision (He's coming back... He always does. )
6. Ant-man
7. Wasp (These two are a duo now, the whole point of their movie after all. )
8. Winter Soldier
So... I think that we got a team already.
I just don't see after the events the world went through that everyone would be just like, "Golly... I really don't see the need for a team like the Avengers despite that I would still be DEAD if it weren't for them."
