New episodes of JLU have been delayed 'til Spring. Some speculate that this is to coincide with the release of Superman Returns. Some speculate that this is to coincide with the release of the first JL season set on DVD.
I speculate that it's because Cartoon Network doesn't know their arse from a hole in the ground. They drove He-Man into cancellation with haphazard scheduling and no advertisement. They'll show all the available episodes of a series in one chunk, then wait six months to ever mention the series again. It's happened to JL multiple times already. Seems like only Adult Swim knows what it's doing. Cartoon Network would rather show six hours of "Kids Next Door" and "Ed, Edd, and Eddy," than put on a variety of shows, maintain a static schedule, and actually use the wide variety of programming rights they own.
Would it be so hard to air Teen Titans and Justice League in the afternoons, during the mid-season breaks? Would it be so difficult to air them even once a week? Is it too much to ask that Superman and Batman: TAS not be limited to late-night Boomerang?
To say nothing of the fact that they've apparently cancelled Teen Titans. What a shot in the foot. Honestly, that has to be one of their most popular series; every friggin' kid I have contact with watches it, and it's a damn good show. Why oh why would they cancel it?
Unless the big reveal comes that they'll be doing "Teen Titans Unlimited" or something concurrent with the proposed Legion of Super-Heroes series. Then, all CN sins will be forgiven.
Except killing He-Man. That was just a crappy thing to do.
