Kabuto has a habit of playing all sides though. When Anko was wondering if he would go after the Leaf or Akatsuki, and then Kabuto said he figured he would visit Tobi "first," well that kinda gives me a sense that he will be contacting Konoha at some point with an offer to aid them as well.

In fact, didn't he already give Konoha a book containing information on Akatsuki? So it seems he already is playing both sides. He has his own agenda.
