Nah. Avengers 5 will be way bigger than the young characters. There are still tons of holdovers from the older stuff and tons of new characters that won't have anything in common with this super-young set of heroes. These characters are definitely being set up for a Young Avengers project, which is probably not going to be a movie. Some of them will be in Avengers 5, too, when it happens, but they won't be the core of it.
