Ever sines news and rummer of Kishi having accepted a new contract that call for an extension for 3 more years of Naruto a time skip has ben spoken off. The Movie dose show A much older Naruto,so that could be an indication of a time skip for Naruto sines I do not believe in Naruto becoming Hokage in Sheppuden after the war but at a much later dated when He is older and has had lessons of leadership from Tsunade. Sheppuden ends in 2014 but Naruto part 3 might go on,Naruto 1 and 2 have 15 years in existence so the possibility of having Naruto go for 20 years makes syndication of the series a multi Billion dollar industry in sales,marketing and merchandising.
