I don't know, somehow, i don't think that venus trap badass guy is gonna fight now, it seems like this arc is calming down now, and they won't inroduce a new akatsuki member just to have him fight Kakashi and die\run away right after his appearence, my guess is that it'll go something like this:

Kakashi: I know your here, show yourself.
Venus-trap-badass-guy: it seems that Kisame wasn't lying about you.
Kakashi: that coat... Akatsuki (assumes battle pose)
Venus-trap-badass-guy: don't get tensed up, my mission isn't to fight you, i'm here only to confirm the boy's survival.
Kakashi: wait, why are you after him? why aren't you trying to take him now?
Venus-trap-badass-guy: 'those question should be directed to our superiors" or 'we've found the current events to be... intersting, we wish to see them continue"

Venus-trap-badass-guy leaves in a cool way, along with another member that Kakashi didn't see.




that's how i see it, a non-combat chapter, introducing a new charecter and giving the fans something to speculate on. another fight that takes 5 chapters would be unacceptable, and if Kakashi manages to finish it in under 5 chapters, then it'll make the akatsuki seem like a bunch of sissies....
