JKTrix is right, although I think some of Sengoku Basara's awesomeness would be lost in an English dub (entirely because Date Masamune's epic ENGRISH would be--literally--lost in translation). Eden of the East might be a bit short for what Adult Swim usually airs, but it's so freaking fantastic that it doesn't matter. It would be quite a wait for the English dubs of even the first movie, though, so I can imagine them waiting on that a bit.

At any rate, I think Fullmetal Alchemist: Brotherhood is just about a given.
