i went on wikipedia for you, & i found out that there is no mention of a season 5 DVD release of Kenny vs. Spenny. Also, as season 4 was only issued on DVD in august 2008, i would not expect a season 5 DVD release for a while.
Update:
With Season 6 debuting this fall I would expect to see a season 5 DVD in late August / early September. Since its a short season of about 10 episodes they will want to try and get the DVD out before they start airing new episodes.
