I wonder if Kabuto is actually a spy, If you get my meaning. It'd be interesting to find out whether he is truthfully spying on Oro, or whether Oro is using him to feed Atkasuki false info about his movements. (With or without Kabuto's knoledge on the later.)

What I think is most likely is that Kabuto is betraying Orochimaru (there has been much hinting about this, even since the very first time that we saw Kabuto talking to Oro). but that (unbeknownst to Kabuto) Orochimaru knows all about Kabuto's spying and is feeding kabuto false information, in order to throw off the Akatsuki.
