The Avengers: Resurrection (title prediction) will feature a swan song of our classic Phase 1 heroes in a final battle to restore humanity. So while the ending of Infinity War was tragic to watch (Peter Parker made my heart ache) we know that the true tragedy is yet to come.

So we generally know how Avengers 4 is gonna shake out. No doubt there will be a few unexpected twists but everyone expects to see the latest roster of heroes restored.
But what about after Avengers 4?
Here's what should happen in the next generation of Marvel movies.
