so...

Heres a prediction we wont find out for a LOOOOOOONG time:
This wont be the last time Oro and Naruto match up...

He obviously needs to match up vs Tsu and Jir again - just because the first time they matched up all 3 were 'messed up' from various things (poison/bloodfobia/no-jutsu's)

The next time they match up they will all be at full strength - and it will be great!

Oro will kill Jiraya (snake > frog) - probably because he was saving Tsunada
This sets up the ultimate Naruto vs Oro showdown...
Oro will have taken away the most key people in Naruto's life
3rd / Jir/ Sasuke (though hell be alive... but lets not get into that right now)

so far - i dont think im stretching very far - but lets go one step further to really really really set this thing on FIRE

Oro released the Kyubi to learn some kind of Jutsu
... if you can draw the next conclusion...
Kyubi 'killed' the 4th....
the 4th is ... obviously...

Oro is the ULTIMATE villain in ANY manga.


.... how you like that one?
