For me.
Avatar season 3.
Danny Phantom season 3.
New Foster's of course.
I have serious doubts about Kim Possible season 4, but I am curious so I'll watch.
More of The Replacements if I can catch it.
Class of 3000 has been pretty promising, so I'll watch more of that.
As for new shows.
Random Cartoons (though I still like the name Oh Yeah Cartoons better.)
I'll check out El Tigre just to see if it's any good.
How sad is it that CN is only twice, how the mighty have fallen.
