I'm guessing it's because their dusting was a major part of the movie (it's what turned the movie from fun and silly to grimly bittersweet), so Disney figured everyone knows about it already.

Furthermore, with the whole "passing of the torch" thing, another Ant-Man movie is in the works, so Disney figured the audience would take for granted that Hank, Hope and Janet are coming back.
