As confirmed in an interview with Stewart and show producer Akiva Goldsman conducted by SFX Magazine, Stewart will retire the character once the third season wraps. Indeed, Goldsman and Stewart said that "Picard" was never meant to run indefinitely, and there were no long-term plans to keep the series around for upwards of seven seasons (the running time of "Star Trek: The Next Generation," "Deep Space Nine," and "Voyager"). Three seasons was always the plan.
