While one of the latest members may not be all new or different, the other sure is. And as many guessed the new Avengers team roster is being joined by Vision and Nova (Sam Alexander).
Technically speaking both these heroes are already Avengers with Vision being a long veteran, and Sam's Nova having joined the team since the AvX event. So far I am digging the changes, and predict we will see a downsizing of the Avengers after Secret Wars given how many superheroes have joined over the last couple of years, and that should be very interesting. I am super excited to see Nova be part of the main line up, he has a great story that has great range from poignant to hilarious.
The remaining silhouettes have to be Iron Man (but not necessarily Tony Stark), Miles Morales, and Sam Wilson's Captain America.
