I don't know if this is a spoiler for Avengers 4 but... 

[[[SPOILERS]]]]

it's speculated by many that in Avengers 4 Banner and Hulk will merge and become a new character with Hulk's strenght and Banner's intellect and who will look more like Mark Ruffalo because he's now in charge, this is him based off of the leaked promo image from a few weeks back.
