Mmmh, gottastudymoregottastudymoregottastudymoredamncoll egedoesn'tletmestudyjapaneseasmuchasI'dlik eto!

Anyway, yeah... I stand by my interpretation of the last page's footnotes. THey say at least something about three boys and their respective battles, so I think we'll see at least a little bit of info regarding Kiba/Akamaru and Shikamaru too.
But, since the next chapter is named Kimimaro's secret, it will most probably be a lot of Naruto vs. Kimimaro, but I don't think it'll be a flashback or backstory yet... most probably, just information on his attacks and his seal.

...also, Naruto is _alomost_ in Kyubi mode. I has to be a good battle, not easy for any of them, but we can't have Kimimaro wiping the floor with Naruto just like that... specially not while half-Kyubi mode is activated.
