RDJ, Hemsworth and Evans all signed a 6 picture deal. 3 solo movies and 3 avengers movies. After that, its anybody's guess as to what may happen as far as them reprising their respective roles. Of all of them though, I think RDJ would stick around the longest, though I'm hoping we get all 3 of them in the mcu for as long as they are able.
