So what power will bolt get the byakugan or sage mode I think he will get the byakugan because Mistsuki has sage mode .
It's the battle of the eyes vs body
He'll have sage mode and here's why. Now in full disclosure I came across this as a counter to Bolt's thrown rasengan being futon related but it led to some interesting points.
Sorry, trying to find the post and thread but having trouble. I'll keep looking but basically Naruto learned rasengan, then he learned how to add futon. Adding futon added the 4 "blades" onto rasengan, however he was never able to throw this form, explained in the fight against Kakuzu that despite the name shuriken it couldn't be thrown. It wasn't until he was training with the sage toads for Pain that he learned to throw it. Sage mode chakra was required to stabilize it after leaving the caster's hand. Therefor Bolt throwing his rasengan is/should be a hint that he will develop sage mode.
I found the thread but for some reason I can't click edit on my old post so here's the link

I'll try and find out why I can't edit it and if I find out how I'll copy it over to this thread.
