It's been confirmed that Janet Van Dyne isn't completely forgotten, even if she's not in the comics or movies after this month for a while.
Janet is the Wasp in the newly released mobile app game "Avengers Academy" from Marvel and TinyCo. It was as Janet that she was even named "prom queen" at the recent launch event for the game.
She's not the classic version of the character, but it looks as if they captured at least some aspects of her personality. And, with the character retiring in the comics and trapped in the "quantum realm" in the movies, at least she's still being acknowledged somewhere.
