Yeah that's honestly the main reason why i won't get exited for a multiple season adaption. I trust that the showrunners get One Piece and i'm sure they'll do at least a decent job at adapting it. I know i'm going to have fun with it no matter how it turns out (except if they somehow make it really boring). But i don't trust that Netflix will renew it until i hear the official word. I'm definitely rooting for it though.
