This is why I hoped for some sort of definitive hardcover book going over the series. I have mentioned this in a couple other threads also speculating on what will be released on the anniversary. Some kind of "Art of Zelda", or "History of Zelda" anniversary collectors edition book. A few series in the past have done this and they normally include things like interviews from the creators, overviews of some of the parts of the series, artwork, concept art and dropped concepts. One section could cover something like a speculative timeline for the series.
Disney occasionally releases their hardcover "Art of" books that cover all these things. And they are always interesting reads.
I love insider information like that, and I believe this would cover everything. Art for the art fans, interviews for the creator fans, and a timeline for the timeline fans. If Halo can have one I do not see why it is impossible for Zelda to have one as well.
