For the past couple of weeks a lot of new information has been released about the upcoming 12th season of CSI. It has been confirmed that Marg Helgenberger (Catherine) will leave CSI in January of 2012. Her character will be domoted as the new supervisor will take her place, Ted Danson (D.B Russel).
In several interview Carol Mendolson (Producer) has said Danson's character will bring a lighter tone to the show providing more humor. I think this is good as i was starting to get board of the team becoming fixated on Haskell. Danson's character will be more of a sherlock Holmes character and will use this to solve crimes.
The producers have also discussed bring sqweegel back for season 12. This would be great. Jorja Fox is returning and being re promoted to series regular. Elasibeth Harnois will join the cast in some capicity.
Hopefully Season 12 will bring back the core values of the show. Solving case with forensics science and lots of it. If the cut down on Nick shooting everybody this would be great.
