Bleach and Naruto still doing well, hopefully One Piece can pick up some momentum over the next few weeks now that we're out of awful filler. The fact people return for Clone Wars is hilarious.

1:00AM: Casshern Sins -> One Piece, +214,000
1:30AM: Eureka 7 -> Soul Eater, +204,000
2:00AM: Sym-Biotic Titan -> Sword Art Online, +64,000
2:30AM: Thundercats (2011) -> IGPX, -98,000
3:00AM: Fullmetal:Brotherhood -> Clone Wars, -3,000
3:30AM: Fullmetal:Brotherhood -> Big O, -21,000
4:00AM: Ghost in the Shell -> Fullmetal:Brotherhood, +29,000

5:30AM: Cowboy Bebop -> InuYasha, +6,000
So the top of the block is doing a lot better as a whole, the middle of the block is doing a worse, IGPX and Clone Wars don't hold peoples attention as well as Thundercats and FMA:B did.
