I still feel a little wary of just outright labelling the current animated continuity "the New 52 animated movies" given more and more they've just been picking and choosing from different continuities instead of being straight-up New 52 adaptions.
Even the upcoming Suicide Squad movie has some New 52 designs (particularly for Waller) but will also see a lot of Post-Crisis characters, classic Dr. Fate, the Crystal Frost version of Killer Frost, and a more Post-Crisis Bronze Tiger. So it's not just the New 52.
I imagine a lot of the initial movie will be spent on developing this version of Superman form, providing some resolution to his relationship with Wonder Woman while re-emphasizing Lois's role in his life, and setting up the other Supermen before the fight with Doomsday (which will probably feature Jason O'Mara's Batman and Rosario Dawson's Wonder Woman).
I'm curious if Jerry O'Connel will still be Superman in this, as well as Juliet Landau as Lois and Steve Blum as Luthor (if he's in it).
I am kind of curious if they'll go with a straight-up version of Kon or try some mix of him and Jon, though I hope we get the former.
And I agree with Superlad that I'm curious if Kara will be in this in some form.
I assume because they want to develop this universe's Superman and his world, which they've only really touched on briefly in past movies, and it also allows them to introduce and develop more characters in this continuity like the other Supermen.
It's probably the same reason they adapted the
Judas Contract with this continuity's version of the Titans instead of just doing a straight-up Wolfman/Perez adaption like they planned on early into the line.
And John Henry Irons made a cameo in
Thrones of Atlantis so arguably this film was foreshadowed as early as 2015
