Thor, Groot, Jeff, Rocket, and Spiderman are expected to get a skin in S4.5 judging by this datamine info from S3.5. What's interesting about this is Immortal Warrior and 2099 are two newly added skin lines in the game. This means we could see Spiderman receiving his 2099 skin at some point in the future featuring the alt color of black red you see in the comics.
