I think Naruto will go off and spend some time to more fully master the Resengan. I think as part of this process, he will think back to the super kyuubi resengan and try to figure out how to replicate that, one handed and everything. And i think for this part Naruto will train on his own, I think he is getting to the point where he is going to want to take responsibility for himself and not seek so much guideance from others. Especially because he failed (for now anyway) for the first time ever. But then again, Naruto really needs to learn some jutsus and get some variety and I dont see him ready to just create new jutsus yet, so i guess he would have to have a teacher for that.
