No Thor and No Vision, obviously because either of those two is way too powerful and would tip the scales of which ever side they're on. I like that because it's just like the original comic where Strange, Thor and basically anyone with real god like power stayed out of the fighting, mostly because they saw that it was beneath them and not worth it
Vision is in it. Paul Bettany hinted that he may switch sides in this movie. Ant-Man is also in this movie and he was absent from the trailer. Rumor is he becomes Giant-Man in this.
