Neutral: Cons
Scarlet Witch’s brother died during a superhuman conflict, so the likelihood of her merely sitting on the fence during a war over how such conflicts should be legislated seems slim.
She’s also arguably the most powerful character amongst the ranks of the Avengers, so it would be something of a waste to not see her in action during the most epic battle in the Marvel Cinematic Universe to date.
The fact that she has yet to be designated a side would seem to suggest that she will join the battle late and turn the tide in the favour of whichever hero she sides with.
The most obvious prediction seems to be that Hulk will arrive late and join one side (probably Iron Man) and Scarlet Witch will arrive late and join the opposite team (probably, therefore, Captain America), but you really can’t see her failing to choose one.
