As ‘That ’70s Show’ enters their final season it appears it will be without two main stars, save for a few guest appearances leading up to the series finale. Executive Producer Dean Batali has admitted that both Eric (Topher Grace) and Kelso (Ashton Kutcher) will be leaving the show following the May 18th season finale, with Eric getting a big send-off and Kelso quietly slipping away. Both are expected back for the series finale at the end of next season.
