It was obvious that Vision was for sure going to die. Beyond that I did not know but I speculated that scarlet witch would live because of the whole vengeance arc and that turned out false. Knowledge from the comics proved that nebula would live. But I also thought more would die from the original team, like black widow and Hawkeye but he wasn't even in it.
I was shocked when Black Panther and Spider man died. But for the most part I didn't really feel much else for other characters.
