Nah, Joel and Ellie's should story should end with the TLoU. They left it on a bitter note, but I think its best to leave the the rest of their story open for intepretation. There no need to add anything more to it imo.
A second game with a new characters, for me (set in the same world) would be most welcome. They could even give cues and hints to the protagonists and characters in first game, or have cameo roles like in Borderlands 2.
Truthfully.. I want a new IP, if anything from ND first. We already have an Uncharted game in the works, so I wouldnt mind them putting TLoU 2 in the back burner for a while. Something new like Savage Starlight (like a mock up) would be quite refreshing to play.
