You do know it was a copyright issue since the designs of playboy sasuke, sailor sakura, hinata road to ninja, and make-out shikamaru were all either in the road to ninja movie and/or part of the ninja storm game series. Heck, some of the animations from ninjas on Naruto Online are from ninja storm. Two weeks ago, someone asked about it on the forums that if sailor sakura would be out in events based on rumors on the china servers and Jiburiru confirmed it was a copyright issue but the new events after that comment, sailor was in great tree.
