I'd have to say that I don't think there will be much 1 on 1 fighting either. All we've seen lately has been 1 on 1 fights, and with Shikamaru leading the team I don't think he'd waste the opportunity for some interesting new combo attacks. Also, the 4 sound nins are accustomed to working together, from what I can see, and I think that they know how to effectively complement each other in battle.
