Sasuke also has the Rinnegan, plus Sharingan. We know both can see chakra, we know the Sharingan can see chakra as color. If that doesn't let you know everything there is to know about a jutsu, i'm not sure what would.

Omnibender wrote: Since Sasuke explains Boruto does it accidentally or subconsciously, I believe that also indicates why Boruto didn't end up creating Wind Release: Rasengan, like Naruto did. Naruto was deliberately training to add as much Wind Release into the Rasengan from the moment it begins forming. Yea, it seems to me that Naruto's Wind Style Rasengan could barely be called a Rasengan, it was already well on it's way to being a Rasenshuriken.

If the sealing scrolls for the Kote are correct, then Konohameru also has a Wind Style: Rasengan, which noticeably lacks the blades yet can be thrown. Also note that in the movie, Boruto's Parent and Child uberrasengan moves EXACTLY like Konohameru's opening rasengan (Shoots off into the distance, then abruptly moves up). We know that Boruto's contained wind release since he made his Vanishing Rasengan, so the connections seem to be there.

So it seems to me that a Wind Style Rasengan can simply be thrown unlike a normal one. The blades (taking the cutting aspect to it's highest) is what makes it the next higher form.
