As reported by TVShowsonDVD Site:
It's no surprise that Paramount would release the successor to I Love Lucy, The Lucy-Desi Comedy Hour; sales of Lucy have been strong. Paramount is calling this the "7th, 8th and 9th Seasons" of I Love Lucy, and it'll be a 4 disc set which runs 739 mins. The set will be available on March 13, 2007.
I'm sure this will be a hit!
