I also think that the Akatsuki's leader is gonna be a female, but i think she might be related to Naruto (perhaps even his mother).
i mean, if Naruto's background story is gonna be revealed, it'll be done by someone who wasn't introduced yet, seeing as the only people who knew the 4th haven't told Naruto anything yet.
3rd- dead.
Jiraya- spent over a month with Naruto, hasn't said anything.
Kakashi- the same as Jiraya.

so having a bad guy\girl telling Naruto his life story could turn out to be quite intersting, it even gives the plot space to advance after akatsuki's arc...
