The Last Dragonborn... well as far as we know your character is infact the last dragonborn, none other has come after him, and if he failed none other would replace him;

As Parthurnax said "even I cannot see beyond time" The Prophecy expected that Alduin would succeed, even though it knew he wouldn't, there was no possible way to see beyond Alduin's possible destruction of the world at the time, so the current Dragonborn was the last forseeable Dragonborn, Therefore he was The Last Dragonborn; if there are any dragonborn in this extended existance then it does not make the player DB any less The Last Dragonborn.
