1 hour premiere at 8PM on Friday July 29th and the following week it airs at 8:30PM.
I wonder what they'll do when Star Wars has another season ready to air. Hopefully they start a second night of action.
The schedule will probably return to basically what we had when Ben 10 and Rex were in premieres. Starting at 6:30 Batman, Young Justice, Ben 10 UA and Generator Rex with ThunderCats topping the block. Though it would be wise to air Ben 10 or Young Justice before ThunderCats instead of Generator Rex which has been flopping hard lately.
More interesting news, Boomerang is finally airing the original Thundercats with a marathon and a regular slot on weekdays at 5PM. Now how about some Real Adventures of Jonny Quest Boomerang? It's long overdue.
