Here you go for that source. I kind of figured it was common knowledge and a source wouldn't be needed. My mistake.

"....I know these characters have these huge legacies, but you have to write them like you made them up. Your versions of them are yours. And for me, this really is the last time they fight. I don't want to say "never," because I don't want to be that guy who comes back and does something he said he'd never do. But I don't foresee myself ever writing the Joker and Batman together again as the Batman and Joker.
I want this to be, like, there's nothing off limits to use, there's nothing off limits they can do to each other, there's nothing off limits in terms of the stakes of the story. That's it."
I love how people can be condescending with their opinions or things like your little "translation" when you really havent kept up with the interviews and what not. Am I the only one who has read things Snyder says? Your "translation" really contradicts what he is saying there. He even told all the other writers of the bat-books that if they wanted to get in on ENDGAME now was the time to do it because they were putting Mr. J away for quite some time.
But he also says this here which is the biggest evidence for why I think their may be a revamp.
"So a lot of the things, like the Court of Owls and the villains — all the stuff coming into the story soon too — was a way to say goodbye to a lot of things I got to write, and I made up, or that I loved that other people made up.....So "Endgame" really is a goodbye and a hello. It really is sort of like saying goodbye to a lot of things that — really, everything we've done on Batman and all of that."
Why would he say something like that? I am not for sure saying it will happen. I more or less just wanted to have a conversation about it. I think there is a chance he will kill of the Joker at the end of his story only for Convergence to conveniently retcon it. And if that were to happen I would totally be okay with it. I would say there is definitely adequate evidence for it to possibly happen.
