Teri Hatcher who has played ditsy mother Susan Mayer for seven years on Desperate Housewives has reportedly told colleagues at ABC that the next season will be her last. A source tells  The Daily Mail that Teri already has a new TV pilot lined up and wants to focus all her time on that:
“She has another production deal in the pipeline and she is in the early stages of developing a sitcom that she wants to start work on immediately after she finishes Desperate Housewives – she wants a new show in time for the mid-January pilot season. Some of the crew are disappointed in Teri, they feel like she is abandoning the show that revived her career.”
The Mail gives no reason why but says, Felicity Huffman is following Teri towards the exit door after next season.  Desperate Housewives’s creator Marc Cherry, had planned to keep the show going for two more seasons, but next season would likely be the last if Teri and Felicity both leave.
