unsure of the future of the franchise, as previous reports have hinted at Matthew McConaughey leading a sequel but Cole Hauser and Kelly Reilly may sign on to reprise their roles. Recent comments from Luke Grimes, Kayce on the show, suggest that this Yellowstone era has ended well, at least after Season 5B concluded.
Speaking to TV Line , Grimes said, “I mean, it’s the end—the end,” he told TVLine. “I don’t know how the show is going to end, and I wa

Yellowstone’s Part 5B has just released its fourth volume, and there are 
two more volumes in store, arriving in mid-December.
