Spoiler Thread: Avengers Infinity War

Has it been confirmed that these movies' plots are chronologically following Infinity? Or it it possible that they may be prequels to Infinity, or as other have mentioned, having another hero take the monikers? My initial reaction was the same as yours, that the ending wasn't permanent. But the more time passes, the more I think it is. Sure there will be another Guardians movie, but maybe it's a good story of an adventure our heroes were on before Infinity, or Rocket forms a whole new group of Guardians. Or we get introduced to an entirely new universal timeline, where our original heroes are still alive. And honestly, I would love to watch any of those movies. So I'm really not having any trouble reconciling the fact that there is another Spider-man movie in the works.

James Gunn said that all the Guardians are going to be in Vol 3. And at least with Spider-Man 2 they've said it takes place almost immediately after the 4th Avengers. I doubt the others take place before it. The writers said that there will be a cost to undoing Infinity War's ending. I think the simplest explanation will be correct, someone like Iron Man or Captain America use the Gauntlet to fix everything but it kills them.
