Yeah, those dudes are all coming back...
Guys .. the snap gets undone. It gets undone in the comics.
The ONLY way to bring everyone back is if someone else gets the Infinity Gauntlet and undoes everything that happened. That's the ONLY way everyone comes back.. We're not just talking about superheroes.
One out of two of every living being in the universe just died. That's death on a unimaginable scale...
It was so much that Thanos needed the Gauntlet to get it done; and it's so much that the only way to undo it is with the Gauntlet itself.
