While some may say this belongs in Future Zelda, I think that this poll describes the whole Zelda universe as one. Basically, does anybody think that soon Miyamoto will retire The Legend of Zelda, just like Kojima did to Metal Gear? Explain.
Nintendo will milk Zelda until people stop buying it. But what he said^
Exactly. Business-wise you will never stop a franchise until it proves itself to be unprofitable. And judging by the continuing "success" of pokemon, mario, and other franchises that have shown positive cash flows, Zelda definitely does not have a certain end in sight.
Personally, I would find it weird for a series of anything to end, especially if it's something that I grew up with and is just so.. old school - lack of a better word.
I don't really know if it's the end, but I don't think a series could last forever, and if does, then I think there are going to be a lot of changes to the Zelda series; to the point where the Zelda now will be nothing close to it.
