Original pitch was it would come at the end of JL2. Darkseid kills Lois, Superman succumbs to anti-life and then jump 5 years later to Knightmare. JL3 (or 2A as they pitched it) opened with GL crashing (Hal in the artwork but not named in the pitch) on Earth. He's saved by Batman, Flash, and Deadshot. GL is looking for his partner, another Earth GL who's presumed dead like most GLs as Darkseid is conquering the universe. Cyborg has built (or helped build) the cosmic treadmill, they plan to send Flash back in time with a message, Batman tells him to change the message.
Knightmare JL steal a motherbox to power the treadmill, evil Superman chases them, basically kills everyone as they get the motherbox to Flash and he just makes it away in time to give Batman a different message so they prevent the death of Lois and Superman going evil.
Based on Snyder's comments we know the the plan has been changed so Knightmare is now the main part of JL2 rather than the cliffhanger of JL2 and first half of JL3 (second half was the big battle with Darkseid and the epilogue). So it sounds like a lot of the set up stuff from the JL2 pitch is either being omitted or maybe just the barebones given in flashbacks or exposition. Deadshot has been replaced by Deathstroke and maybe Joker, and flashbacks to Robin's death are something he's spoken about (with the potential for the Knightmare story and Robin's death or just Robin's death to be told in comics as well) so that might be in there. But it sounds like the broad strokes are still the same.
No mention of ever going to Apokolips or what Martian Manhunter's role would be. Even Darkseid never shows up in the Knightmare future in the pitch, just evil Superman.
Evil Superman adds nothing to Clark's arc because it's just reversed. He submits when Lois dies and is just Darkseid's puppet/evil from then on. There's no conflict suggested in the pitch or by Snyder to the best of my knowledge. None of the usual, Superman breaks the control when pushed to kill displaying that his will is stronger. He's used as the main villain, kills the League, then it's all undone. No character growth at all.
