Well, Falion claims to have seen them while traversing planes of existence (there doesn't seem to be any reason for him to lie about that as he isn't one to overstate his talents or accomplishments).

Also, Arniel attempted to recreate the incident in which the Dwemer disappeared and as far as anyone can tell, he succeded since he disappeared too.

In theory, there doesn't seem to be anything standing in the way of a Dwemer return storyline. (Skyrim's extensive featuring of Dwemer locations, lore and again, Arniel's Endeavor kind of seem to set this up too)

Whether or not this will actually happen is anyone's guess. Besides, TES6 is still years away. Best to wait and see.
