Lol OP came out in 1997 I wouldn't call 2012 rushing it by any means. I was truly asking what happened to the treasure or if they are still even thinking about it but I will answer your question since you asked.
I'm not going to lose any sleep if it, Naruto, Bleach, any of em don't end. But I do think that any series (anime, sitcoms, movies franchises, etc) that goes on for too long really gets away from what it was originally about and loses the standard of quality. I do think Bleach is by far the worse one. I decided to choose 1 ongoing series, my dad likes Naruto too so I chose it instead of One Piece (which is a pretty good series if you don't care about the "one Piece" like me). I just prefer anime that wraps up in 30-40 episodes myself cos I wanna get into something new. There's so many great series out there and I feel like they rarely get mentioned here because all anyone watches is Naruto, OP, DBZ (dbz is epic, the other versions gfto) Bleach, Death Note, well the hella mainstream ones.
But I really was just asking about the treasure. Do they still talk about it?
They will find it, but I hope not soon. And the treasure is just a metaphor (I think), and for Luffy the treasure just his nakama's and for Nami the one and the same treasure is money, gold... :D
