Yep. They need flexibility. It makes zero sense to air an uncut opening and yet cut epilogues when in some cases, they contain material that you do not see in the next episode.
Instead they just seem to cut everything the same way no matter what, which is really rather lazy.
A third hour would be awesome.
They also need another good series once Rave Master is finally off of the air. It'd be great if rumors of Ergo Proxy or Black Jack came true. It doesn't really matter, it just neeRAB to be something interesting.
