Neither

Neither. Probably none of the new Avengers either. Definitely not Thor, Spiderman, Black Panther, or Ant Man. I can pretty much guarantee they won't have the balls to let any of the heroes kill each other, and any deaths will be collateral or caused by Crossbones.

I'm still hoping Black Widow dies and it kicks off World War Hulk.

They cant make money if they kill off main characters.

How is this even a question?

Lots of American lives were lost

This is how I imagine it. I expect Cap or Tony to die at the end somehow by HYDRA.

Robert Downey Jr. already didn't really want to show up for Iron Man 3.

Yeah, I can't really find a reputable source for RDJ's contract. I remember he only agreed to do two other movies after IM3, but other sources are saying he's contracted for Infinity Wars.

Same with Chris Evans. Most people believe CW is the last movie he's contracted for, and he once expressed interest in being done with Marvel by 2017, which is why most people think he's going to die. But now he's saying he'll do any movie Marvel wants him for.
