I agree. They haven't given an official reason as to why, but there's unverified speculation that someone has objected to the name. Amazon Prime??

Just had a look on the web; aparently, 5Prime's launch has been put on hold until the Spring and will no longer be called 5Prime. Viacom are rethinking both the strategy and the look.
Perhaps they're thinking of calling it Paramount instead (though their branding seems to suggest that they want their channels to be prefixed by 5).
