I wonder if it will be elaborated on whether the Tomorrowverse is connected or not. Some think this is a similar animation style... eh, not sure.
Quite possible. But I think we should wait until Green Lantern is out to see what they do with the universe.Huh. Maybe Man of Tomorrow and Justice Society are set in the new timeline but before Apokolips War, thus explaining why Barry doesn't remember the old timeline.
Oh I absolutely take this as the a solid connection between the two shows. Killer Moth is the only issue, but I think it can be explained that he's simply a different version of the same character like Clayface. I'll post a simplified order I made when I get a min. I also included Legion Of Superheroes but that's just my head-canon.
