It has been rumored for months, even dating back to last year, about the WWE Unifying the Intercontinental Championship and United States Championship. According to several sources, this idea has been nixed and will not be a topic of conversation for the time being.
Officials feel that with the expansion of Raw to three hours, along with Smackdown, that there are just enough championships on the roster. Expect the WWE Intercontinetal Championship to be defended more on Raw over Smackdown. This was already noticed when the WWE had an open vote of the IC Title to be defended on Raw this week. Christian will defend the Intercontinental Championship against an unknown opponent.
The United States Championship, still held by Santino, is expected to be used more on Smackdown. Officials feel the Intercontinental Championship is the more prestigious title, and if defended more on their "A" show, the fans will be drawn to assuming that belt more important.
Also, there is no plans of unifying the WWE and World Heavyweigth Championships either.
