Premium cable channel Encore Westerns will begin airing Gunsmoke in January of 2010 according to The Hollywood Reporter. The show has previously aired on Encore Westerns but hasn't been seen in four years. Rawhide and Have Gun, Will Travel, also from CBS TV Distribution, will debut sometime in 2010. Encore Westerns is one of seven Encore channels owned by Starz Entertainment, it seems, none of which I have ever seen.
The article quotes Nancy Silverstone, vice president of program acquisitions for Starz Entertainment as saying "our Westerns viewers are made up of true and diehard fans of the genre. They were devastated when 'Gunsmoke' went off the channel four long years ago. The series is still relevant today as it was over 50 years ago. We have no doubt that our fans will also be excited by the addition of the classic series 'Have Gun Will Travel' and 'Rawhide.'"
