It’s been months since Season 6 ended. There’s a “Poll” in FOX Broadcasting Company website in 24 TV show page asking “Have you purposefully stayed away from hearing any new information about season 7?” well..
According to wiki it is currently delayed due to the 2007 Writers Guild of America strike. In a press release, Fox stated the new season was being postponed to ensure that it can air uninterrupted, in its entirety.
Season 7 will begin and end at 8:00AM and will begin airing in the United States when the writer’s strike is resolved. The producers of the show have confirmed there will be no season 7 prequel bridging seasons 6 and 7. The initial back story will feature Jack Bauer on trial for his actions in the pursuit of justice. Meanwhile, a major national security breach occurs when the firewall responsible for protecting America’s government computer infrastructure is breached. It will also feature the show’s first female president, Allison Taylor, played by Cherry Jones, as well as the return of Carlos Bernard as Tony Almeida, one of this season’s main antagonists, who was presumed dead in Season 5. This will be the first season to see Jack not working with CTU because it was disbanded by the U.S. government at some point after the events of Day 6.
