Crystal Dynamics' upcoming Avenger game looks to be a destination for players for a long time. The developer has already said that it plans to support the game with continual updates. If a recent data mine from Reddit user 6plus4equals52 is to be believed, the game code already contains references to the popular Marvel characters Kate Bishop, She-Hulk, and War Machine, so it seems likely that we'll soon see these characters as DLC additions.
If you're not familiar, Kate Bishop also goes by the codename Hawkeye as she is a highly skilled archer and a member of the Young Avengers. She-Hulk, aka Jennifer Walters, is Bruce Banner's cousin, and she received Hulk-like powers after getting an emergency blood transfusion from Bruce. Finally, War Machine, aka James "Rhodey" Rhodes is a good friend of Tony Stark and wears an advanced armored battlesuit – come on, you don't really need us to explain this stuff to you.
