I to noticed that figure in the back ground, but she does look like a team up just like Winter Solider and Black Panther. And I'm hoping she isnt, with the talk at Comic Con of new lines of MsMarvel and She-Hulk so maybe a movie in the works. And hopefully if they going to bring out more female heroes then they can look a little deeper into what fans would like to play. Already Wasp and maybe Ms Marvel as team up discs, bit what females could we see.
I agree with Rogpalmeruk that maybe Spider Woman ( Again with a movie in talks this could be a good idea to jump on that band wagon early.)
She-Hulk (already on our tv in Agents of smash on Disney right now)
Scarlet Witch (a lot of fans asking for her already, and be a great double pack with Quicksilver)
Dagger (again spoken about at Comic con, her and Cloak would make great figures)
Elektra (By what people are saying she is a must for Infinity. People are saying the character is to violent...so Gamora with a sword is any worse? And let's be honest that would bring us Daredevil.)
