First off, these are not my words. I'm pasting from a different link.
-THE RUMOR ABOUT TESTING TT SHORTS ON BRINGING BACK THE ACTUAL SHOW WAS TRUE.
-ALL VOICE ACTORS WILL BE TOGETHER
-Still has that kid-ish appropriate.
-Full half-hour shows!
Bad News( Changes. it depends if its good or bad in your view):
-The title will be: Teen Titans Go!
-Different drawing styles
-More focused on humor
-It's more of a filler episode as being teenagers during their free time
-Premieres in 2013.
