And yet somehow it's a DOA show actually getting 52 11-minute episodes!
I think there's some kind of a "shareability" between CN and [as]; after all, that's how we got Beware The Batman, Sym-Bionic Titan, and Thundercats, as well as I believe old Samurai Jack. In those cases, owned by Turner seems to be owned by Turner. We also know there was a "shareability" between TCM and CN when they acquired the Month of Miyazaki in 2006.
I think a lot of it depends on the fate of Tokyo Ghoul, or what Toonami would acquire just to air at 2 AM. If Ghoul is headed to 2 AM after its first season (Not sure what the hell they'd air at 2 AM for 2 weeks after Gundam Unicorn ends but work with me), then JLA might not be a bad candidate, doubled-up, for 2:30 AM, if it can pull a "Star Wars: The Clone Wars", sorta like the first season did with a Midnight rerun back in 2009 on [as].
One thing's for certain, I'd be a HELL of a lot more likely to follow it there, and it would be a free way to get some DC action back on Toonami for the first time since the Bat-Blowout for Beware The Batman in 2014.
