One can only speculate what happened to him. While I agree he will probably make his return during another disaster near the final destruction of Nirn and fulfill his destiny as the World-Eater, Alduin is a special creature, even amongst his bretheren. Perhaps his soul is so powerul, the dragonborn is incapable of absorbing. Maybe his soul simply went to another place. Perhaps even Alduin can experience death like the rest of us.
