do we know if they will put one piece some day? im new too crunchy so im just asking :)
One Piece is licensed by Funimation and is their "tentpole" simulcast. (much as Naruto Shippuden is for Crunchyroll), so the answer that it is quite unlikely any time in the foreseeable future.
Naruto and Bleach, perhaps the bipod simulcasts of Crunchyroll when Bleach returns, that is...
Edit: ahem, Naruto... Baruto is an ozeki...
