I honestly don't understand the reason to think about when it'll end. And I especially don't understand people, who want to see an ending soon. In my opinion it means that such a people don't really like Conan. Becuase as for me, the ending is the saddest thing in any mystery. When you finished another mystery novel, that's it, it's finished, there's nothing else about it. No more tricks, no more suspense, nothing. Such a long story is part of Conan's charm. None in the right mind should start to read / watch it because of the ending. The process, that's what really important. When you collecting clues, trying to get deeper into the mystery, that's the fun. Not just a couple of "epic" revelations and "everybody died", or "and they lived happily ever after" in the end. I can see why people want to see an ending of some action series, because most of them is only about epic fight in the end, but since we have a mystery here, it's better for it to go forever. I really want Aoyama-sensei to continue as long as he can draw. I don't want Conan to end.
