Pictures from the March issue of Saikyou Jump, on sale 2/4, reveal that the Rock Lee no Seishun Full Power Ninden anime that had been previously announced will be airing on TV Tokyo on Tuesdays at 6pm in Japan, Bleach's current time slot.
It is not yet known if the Bleach anime is ending, taking a break, moving time slots, or sharing the time slot with the Rock Lee anime. Bleach has moved time slots 3 times before, the last time being in October of 2008. Though with only about a dozen chapters out, it's hard to imagine there is enough material for a full 13 episode 22 minute series.
The Rock Lee series will be animated by Studio Pierrot (Naruto, Bleach). The full TV series name is Naruto SD: Rock Lee no Seishun Full Power Ninden with SD also standing for sugoi doryoku (incredible effort).
