personally, I feel like, as of last week, Toonami's had a phenomenal lineup that will lead to a pretty solid future. I can't see it going anywhere anytime all that soon.
remember that when it first died, the block was populated with really lame american series and third-rate toy-sales anime for months before going off the air.
One Piece is a real gem and I think taking it off is a mistake, epecially for tokyo Ghoul. the TG manga is selling wel, but i feel like the hype train's slowed down significantly. we'll get tokyo ghoul, gundam IBO season 2, AoT season 2 and then, when those end, (along with DBZ Kai and GITS: SAC), hopefully One Piece will continue its run
