Kevin Costner's departure from Yellowstone opens up new possibilities for the franchise's future. While season 5 is still on hiatus due to the ongoing writer's strike, the show is projected to conclude with Costner before he leaves the series for good. However, the franchise will expand with spin-offs and a sequel, which will star Matthew McConaughey and likely cover the war for control over the Yellowstone ranch and Broken Rock reservation. With a fresh perspective, the McConaughey-led spinoff could capture the magic of True Detective and be an instant hit. Additionally, two other spinoffs are in the works, and they open the door for beloved characters like Rip Wheeler and Beth Dutton to reappear in other series. Even with Costner's exit, the overall Yellowstone universe will thrive.
