After the show was axed in 2008, there were many rumours about a possible revival by Nine, Seven, Ten, or SBS.
SBS Programmer Shawn White denied the show would be revived on their channel despite rumours with Nine CEO David Gyngell notably 'interested' in the idea soon after the cancellation, only to turn it down days later.
The Seven Network expressed interest since bidding for the show after the seventh-season finale; however, denied any and all revival occurring a week after the 2008 finale on morning program Sunrise.
