All of that is true, but...

Jiraiya, and all of Konoha for that matter, dont' give a shit about Sasuke. Jiraiya's initial reason for the 3 year training was to prepare for Akatsuki, and not to recover sasuke. Jiraiya even said that Sasuke was a lost cause, meaning it didn't matter if he became Oro's pawn because basically he already was. Naruto's the only one who wants him back in order to fullfil his promise.

I don't think sasuke's gonna be in another chuunin exam (who's genious preposal was this again?), but I'm not counting him out of the picture just yet.
