Come to think of it, there is one thing in Naruto that I dearly would have liked explained, but Kishi swindled out of making an explanation.

During the Elemental Change training with Yamato, Naruto asked about how Shikamaru's shadow techniques figured into that whole thing and Yamato said that he'd teach him about that kind of stuff later and for now they should concentrated purely on the elements... but he never did!
