I hope that if Season 5 sales did poorly because of no Bo & Luke, that won't hurt the release of future seasons.... I was just about to post something asking about this today myself, I hope the news comes out soon.
Forget the absence of Bo and Luke on Season 5 . . . What about the big screen version? I hope the remaining season sets don't get shot down because of the flop that the movie became.
Yup, Season 6 features the 2 part episode "Undercover Dukes" where Bo and Luke take part in a government sting to bust some crooks under the guise of returning to the NASCAR circuit.
Many say, even this late in the game, that it was one of the finest episodes in DUKES history.
