The Dovahkiin's survival can attribute to a great many of things. If a TES6 would ever be made, a re-emergence of the Thu'um could be a direct result from the Dovahkiin passing on knowledge. They may even disappear from public sight, wandering into the time wound to wait for Alduin's final coming. We probably won't meet the Dovahkiin, but they may leave a legacy.

As for the Dragonborn's final act, it may yet be told someday. The whole Aldmeri Dominion vs. Empire war would never work out grand scale in Skyrim. But how about a first-of-its-kind RTS game in the Elder Scrolls universe. Open ends are always good, it means something or someone remains usable in later titles.
