I kind of hoped for him to talk to Sasuke directly as well as Hashirama.
"Maybe I failed the generations after us, but I did what I thought was right. However, that's the past. Sasuke, you are the only living Uchiha after I die in a few moments... Walk the path you think is right, but don't drag anyone with you if it's not the correct one for everyone else... Hashirama, we never got on the same page in our later years due to turmoil and my own ideals being so strong, but you were a great opponent, you were like a brother. We can't be brothers after everything, but we can be comrades in our final moments in this world."
Yeah, I know, he'd never say that.. but you never know what someone will say once they go through something like that.
