At this point I'm wondering if anyone on Tony's side besides Rhodey (and maybe Vision) is really on his side.

Black Widow is tight with Hawkeye and Cap, though it might be good storytelling to have her genuinely disagreeing with them. Though conversely...Hawkeye could be a double-agent on Cap's team.

Black Panther was on Cap's side in the comics and Chadwick Boseman has hinted that t'Challa's role in the film may not be as clear-cut as "being on any one side." Might be ballsy/cool if they show the Panther kinda messing over both sides in a way that's advantageous to him/Wakanda. Not in a villainous/hurtful way, but showing that he's a cunning manipulator who looks after his own nation's interests first and foremost.

I do think we'll definitely see some side-changing at some point in the movie, and that's not even getting into the long-rumored Spider-Man cameo/role (which I kind of suspect is going to be more towards the "cameo" side than "major supporting role.")
