Shrug of God: In the New 52 comic verse, universe 12 follows the Batman Beyond time period. The writers more or less claim it is the same verse as the DCAU or at least close enough to it that they don't really contradict each other.
What Could Have Been: Several TV shows were considered but scrapped. These include a Catwoman spin-off, a Teen Titans TV series (focusing on the original line-up, this was before the 2003 TV series), a Zatanna TV show, a Lighter and SofterSequel Series to Batman Beyond focusing a now-married Terry and his family residing in a terraformed colony in Mars, a Lobo TV series, a The Question spinoff series, and a fourth Batman animated series set in the 22nd century. Superman: The Animated Series was also considered to be a Justice League series, where Superman would team up with various superheroes before forming the League at the end of the first season.
