-Eternals ==> Eternals 2

-Wanda ===> will not return

-Doctor Strange ===> Avengers: Kang Dynasty or Secret Wars, but Doctor Strange 3 if that releases before Avengers 5 and 6....

-Spider-Man ==> Avengers: Kang Dynasty or Secret Wars, but Spider-Man 4 if that releases before Avengers 5 and 6....

-Thor ==> Avengers: Kang Dynasty or Secret Wars, but Thor 5 if that releases before Avengers 5 and 6....

-Hawkeye ==> ????????????????????????

-Jack the Werewolf ===> ??????????????????????????/

But, let's not forget, that that multiversal ride in Avengers Campus is gonna feature mostly all of these characters, if not all of them...

There's no point guessing for most of these characters since, like you said, we literally have no idea when or where or if they'll show up again. We do know that Spider-Man will get another trilogy, however.

@SpiderFan2104 We don't know if Wanda will return or not yet.

Spider-Man 4 will release before KD and SW, and that will be when he returns.

For the love of god, you have to be the most gullible person ever if you really think Wanda is gone. If not in Agatha, most likely in Vision Quest, and if not there, then probably Avengers.

It’s 80-20. The evidence is 80% she’s not dead, but until we see her in the flesh alive it won't be 100%.

I agree with SpiderFan2104 on Eternals, Strange, Spider-Man, and Thor.

Wanda could be in Agatha, probably in Vision Quest, and Avengers 5 and 6.

Hawkeye (Clint) could show up in Avengers 5 and 6 but may not be a major player. Hawkeye (Kate) will show up some time in Phase 6 (maybe Phase 5) most likely.

Werewolf by Night could show up in Avengers 5/6 and I personally think he'll show up if Midnight Sons does happen.
