We are not going to see another timeskip atleast not anytime soon. If Kishi feels like he needs to make Naruto better then he could just put him through and off screen training session like he used to. I can't believe that people still want to see more of the Kyuubi( Naruto using the Kyuubi) at this point because frankly its rather boring, it detracts alot from the fact that they are ninjas and nothing good has ever come of it.

Naruto's Kyuubi history. Used it against Haku, nothing came of that, against Oro again nothing, against Neji once again nothing, against Gaara the only purpose it served was to eliminate Shukaku the battle was a draw, against Sasuke nothing came of that, against Deidara once again nothing, then he used it again against Oro and once again for nothing.
