Detective Conan is far from over.. Gosho Aoyama got problems on the ending? what do you think?

That's what I thought of, because it's really hard to end a story, especially like that one, Gosho Aoyama maybe is trying to fit the best endings, and the best ending would be Shinichi will be back to his real body. But is it really a best ending? No, because Conan will be gone, and even if everybody in the story will know that Shinichi is Conan, well, don't you think it's too bad? They will miss the naught wandering kid who's very curious of his surroundings. I think Gosho Aoyama is trapped and is thinking of the real best way to end this story, but I hope it will not end soon, because it's such a great story. Then, Im just curious if Detective Conan is the longest anime running of all times? Is it? 11 years now right? Anyway I think the best ending is not to be realistic, I'm trying to say that the ending should be like this, Shinichi will have his body back then there's a real Conan living out there, so, it's all fun.. what do you think?
