I think we'll probably see more of Tingle in the future. But I don't really care either way. He was annoying in The Wind Waker because he charges you so many rupees for deciphering a stupid Triforce Chart, but that aside, he's not someone to hate with a burning passion. I mean, he did give you a epic Seed Satchel and Sea Chart in OoA (don't know about OoS cause I haven't played it) for free. =P And he was kinda humorous in Majora's Mask. But I haven't played the other games that he's in, so I can't really say anything about those.
