User blog comment:KrspaceT/What's going to Happen with Naruto and Bleach.../@comment-5926029-20130807050423

From what I can see,Bleach will likely end awhile before Naruto goes into the filler arcs.I understand your concern about this issue and some have brought it up on Toonami's Tumblr.Even though those two give the highest ratings currently,I think that Toonami hopefully will be able to get more shows to fill the gap.It's still too early to tell .

Unfortuately,there is little to no chance that Toonami can get Dragon Ball back since all three shows are owned currently by Nick. Fairy Tail might be possible sometime in the future if Toonami can get the rights to it.Many fans have requested it and would boost ratings I'm sure.Naruto Shippuden,Inuyasha the Final Act,a Gundam show,Yu Yu Hakusho etc. could be possible in the future too.

Naruto doesn't go into the huge filler season until 2015 at it's current rate and Bleach has at least a year left.Toonami now has Sword Art Online and One Piece which could boost in ratings in the future.But like I said there really is no way to tell this early in game.

Note: According to rumors, which haven't been confirmed yet ,the Bleach anime might be starting back after the manga ends.The manga is on it's last arc and is going to be ending soon, almost definitely before the end of the Bleach anime on Toonami.If the rumors are true and anime continues afterwards,I'm sure Adult Swim would endeavor to aquire the new season.
