This arc is going to have a huge fixation on elements, especially wind elements.

I hate when they do stuff like that, because it's so ridiculously timed that its impossible to suspend disbelief. Over the entirety of the Naruto series, nobody observes Naruto's chakra element until right after the big reveal by Kakashi? It's like Kakashi brought out the prize pony, and now the filler writers are going to beat it to death before its real purpose could even be utilized.
