Nightblood - spoilers for ALL Cosmere including Wind and Truth

It seems like Nightblood has grown quite a bit by the end of WaT. He's able to copy the surges of ALL of the Honor blades. He chose to NOT absorb/kill Szeth. And I think I remember reading Sanderson claiming that NIghtblood is extremely important to the entire Cosemere.

With tjat in mind, and with the coming time jump, where do you guys think we see Nightblood? Will he ever be more than "Destroy Evil"? He claims himself that "I'm a REALLY good sword!"
