honestly, i don't think it'll be that quick. naruto would take a pretty long time to train i think. there's also kisame to worry about and i think kishi might address that soon.
i know, such a pain waiting for everything to fall into place!
you have a point ... but as I look back at most all of Naruto's trainings, He seem to get through most of them pretty quickly. like sage mode was only 5-6 chapters (minus all the fillers) .. wind training was fairly fast also ... I do understand that training to control a bijuu is much more than either of these, but we all know Naruto's determination, and willpower to get things done.
I personally think that Naruto will never fully control the Kyuubi .. but more or less will be able to use most of its powers.
Kisame was a good point also ... I can see them fighting, and Naruto finally gets shown being able to use the demon cloak (past 4 tails) under his own will.
that would definitely be awesome!
Correct me if im wrong but i just thought about this...
I remember in an early chapter maybe even pre-shippuuden that it was said when Naruto transforms it actually starts to kill his body, or something to that effect.
If this is the case, it may be more like sasoono is for Sasuke .. except instead of depleting chakara, it starts taking life away from Naruto. Thus Naruto cant just use it whenever. And maybe this doesn't happen to Bee because of differences in the nature of the beasts.
