Fans of Cartoon Network's DC animated block, get your online petitions started.

Both "Young Justice" and "Green Lantern: The Animated Series" were notably absent when the network announced its 2013-2014 schedule today, confirming to many that both series have been quietly cancelled. The writing was on the wall, particularly in the case of "Young Justice", whose tie-in comic was cancelled recently and one of the voice actors on the animated series leaking that production had stopped since the conclusion of its second season.
The two series met the same fate as some of the network's previous original animated series, such as "Thundercats" and "Symbionic Titan", in that the cancellations were never formally announced, the series were just quietly not renewed. However, "Green Lantern: TAS" co-creator/producer Giancarlo Volpe confirmed the cancellation on his Twitter, stating "This time we knew. They just didn't want us to announce it publicly until they did."
The news isn't all bad: the cancellation of the series does not mean the cancellation of the DC Nation block of programming. Rather, two new series will see their debut with the network's new season.
Premiering in April, "Teen Titans GO!" will feature the return of Robin, Starfire, Raven, Beast Boy and Cyborg in more comedically skewed adventures. The voice cast from the original "Teen Titans" animated series will return for the series, which will revolve more on funny side of the superhero business and the awkwardness that comes with superpowered teens living together under one roof.
"Beware The Batman" is purported to be a new take on the classic Dark Knight character, bringing in the core characters fans know and love along with a line-up of new villains never before seen in animated form. The series will combine the action and mystery so characteristic of the Batman, while claiming to "redefine what we have come to know as a 'Batman show.'"
While the new series serve to soften the blow, I know a few people who will be genuinely disappointed to see both of these shows coming to a close, particularly the "Green Lantern" series. What do you think of Cartoon Network's shuffling of its programming deck?
Please stop trying to copy Marvel!!!! The Ultimate Spider-man on DisneyXD is horrible and those Teen Titans Go will be just the same. GL and Young Justice have been outstanding! The story arcs and the amount of characters brought in on YJ has been the best. Finally, CN had DC cartoons that didn't focus on Batman(still the best). Why are network execs' so into appealing to 5-7yr olds. They buy nothing! Those of us capable of posting a comment are your advert's demographics and have money. No sense in tuning into CN. Good Bye! and Good Riddance!
Normally cancellations don't warrant that much of a reaction from me but I have to admit my jaw dropped momentarily about Young Justice being cancelled. I'm a little behind on the episodes but I love that show.
If that 'Teen Titans Go' is going to be exactly like the shorts, it's going to be awful.
"Young Justice" is the best thing ever. Big-ass arcing stories, reaching deep into the DC bench of characters- I could go on. I doubt anything as good will replace it.
