Eldarion had successors, we just don't know who they are. Listing "none" as his successors is inappropriate.
I don't think that the successors of Eldarion should be listed as "none." This would indicate that he had no successors, which is not indicated by Professor Tolkien. Indeed, he stated that Elessar's heirs ruled the Reunited Kingdom for many long years into the Fourth Age. It would be better to say that his successors are unrecorded, or something to that effect.

I think he will be the main protagonist in LOTR 4.
