first of all narutos been around for almost six years. its about damn time that he started tapping more into his jinchuuriki power especially since hes going to be facing dangers waaaaaaaaay above his level. narutos growth as a jinchuuriki would be incrediblely slow if he could only control a small amount of that power until the end of the series. there are other jinchuuriki with the tailed beast of 2-8 out there. i bet they can control most of their strength. naruto, who host the most power one, would be seriously behind if he could only control a little of its power. you also forget that the seal is breaking which is one of the reasons for his incredible growth.

orochimaru is a legendary ninja. i would expect him to be able to fight off a youma for a while, and if you havent noticed, he isnt particularly winning this fight either. the akatsuki has taken down bijuu before so oro should be able to hang. and yeah, naruto is only using 4/9 of the kyuubis strength. thats not even half and oro cant land a solid hit off of it. not to mention that black sphere is making oro shit his pants. multiply narutos current strength by two, and i garauntee you oro would get owned.
I doubt Oro will stand there like a plum waiting for that black sphere to hit him. Oro is smarter than that. I still think someones gonna interupt the fight or throw a wrench into it. I betting Sai will snap outta his phase of Naruto being a Monster and get back to his mission. That or Sasuke will come out and own Sai before his plans are set into play.

Oh the many possibilties...
