So I have some things to share about Endgame
Basically all major survivors die. THATS TRUE AF.
Leaks suggesting 4 of 6 OG dying are fake (or rather are ⅔rd true)
All OG dies. Remember scripts were written before.
Rdj and Evans wanted to leave MCU. Russos know that fans would want a happy conclusion, but they were adamant in making this a deathfest, too emotional and cathartic.
Both will die. They're trying to play reverse psychology with 'Cap dying'. And trying to mislead Stark's death.
WarMachine and Hawkeye also have last outings. They were below the barrel characters, expendable.
Thor and Hulk would be surprising due to Ragnarok. But reread the script point. At that time, Thor was not that cool. They tried to develop his character with Infinity War so he could be killed later on! And revert Thanos killer theories. For Hulk, it will end his arc (he was already just alive due to merchandising desu) by killing him as well.
This will effectively end what was set up in Phase 1. Natasha was the safest before since she was A Female hero. But now that Marvel/Wasp is here, they didn't want to pull their punch. On OG six. They also decided to experiment more on chronological order, to give her a prequel.
Nebula's arc will end as well. She existed in Gotg mainly so her arc will end up in endgame.
Most surprising : Scott and Rocket. The later, "The Jerk" will die. But he would definitely return and be much significant in gotg3. Finally before you kill me for mentioning Antman, lemme tell ya that it is true. He will be integral to endgame ofc, but won't end up alive. The sequel will be 'The Wasp' led one. I'm not saying Rudd won't be back for it, he likely will.
This is accounting main chars. Idk about asgardians, possible that they survive with Valkyrie or they die, ending Ragnarok.
But in probably what will be a HUGE GUT PUNCH, Endgame will be a bloodbath.
