Its been long overdue for a new opening to come out, it usually takes every 30 episodes for new openings to come out and this is the first time, it has been longer than 70 episodes and still no opening 16. I am tired of Opening 15 which is We Go, its enjoyable but gets boring. I hope for new opening.
The new OP comes out on the very next episode.
The title is "Hands Up!" by the singer Kouta Shinzato. The ED of 2 hour anime special "Episode of Luffy" was also sung by him. http://www.youtube.com/watch?v=CDLpvL62Gqc
