Yup, I'm pretty sure that's what Feige was talking about. Falcon has already been rumored to be the next addition to the Avengers, and the fact that a new Avengers comic and cartoon (Marvel Now? Sorry, I haven't been keeping up in the past year or two) features the 6 Movie Avengers, plus Falcon, seems to back that up.
Which might answer the question we've all been debating about expanding the roster for Avengers 2. Sounds like Falcon's the only n00b. But I'm still holding out for more additions as Phase II wears on.
