Cartoon Network did
bring Young Justice
and Green Lantern
back in January after doing this exact same thing with them. They'd probably lose money if they breached their agreement with WB to air the episodes. Broadcast networks often cancel shows without burning off the episodes, but cable networks usually have to show the entire season of a series sooner or later, even if it's rescheduled. Not to mention that CN invested money in making the episodes in the first place.
