Could Courage the Cowardly Dog Be Coming Back to TV?

Recent buzz on Tumblr and Buzzfeed would lead one to believe that yes, Courage is returning in 2012. Unfortunately, I can't find any solid sources so I wouldn't take it with a grain of salt.  The Youtube video proposes that it's a "leaked trailer," but it was uploaded Sept. 2011.  The production values seem a little bit lower than one would expect from a Cartoon Network promo.  I'd file this under "too good to be true".  Plus, I'd much rather see Dexter's Laboratory come back anyways.
