So basically, they could be introduced in Avengers 2, and then audiences can catch their solo (duo? trio?) film just 6 months later.
Then the question is, which female Avenger will be added to the permanent roster in A2 if Jan is a background character. Although I would prefer to see the Scarlet Witch, I would be willing to bet that Danvers gets the call. It will be interesting to see how her origin and powers are handled if she is added to the team.
