Maybe they'll introduce the term megaverse or omniverse; the encompassing term for the collection of different multiverses (Marvel did it, I don't know if DC will too). It's the only think I can think of. There is one other. Maybe he is Clark Kent but not from the Smallville multiverse, but I don't want to think that that's likely. Those are just my theories though.
