Obviously the three Jokers are Batman '66 Joker, BTAS Joker, and TDK Joker.
From Newsarama's spoilers, the three Jokers were the original, the Killing Joke Joker and the Endgame/Snyder Joker.
Why? Why is someone spoiling this? Everyone is going to be buying this next week so why spoil it now.
DC sent out review copies. Reddit got ahold of one and spoiled it, Bleeding Cool reported it, and according to Bleeding Cool because they reported it, the major Comic News outlets are now given the go-ahead to spoil it.
There's way more that happens since it's an 80 page issue (there's Legion hints and Ryan Choi being the only person who can save Ray Palmer, Aquaman proposing to Mera, Green Arrow and Black Canary knowing the spark between them is real while Wally talks about the ten years taken away, etc). Spoiling it a week ahead of time gives DC publicity ahead of Rebirth. It's pretty smart strategy even though the backlash is gonna be major.

But in the current, digitized world, trivial information is accumulating every second, preserved in all its triteness. Never fading, always accessible. Rumors about petty issues, misinterpretations, slander... All this junk data preserved in an unfiltered state, growing at an alarming rate. It will only slow down social progress, reduce the rate of evolution. You seem to think that our plan is one of censorship. What we propose to do is not to control content, but to create context.
