The sun may have set on Yellowstone, but its legacy burns brighter than ever. With Luke Grimes leading the charge into a new chapter and multiple spinoffs on the horizon, Taylor Sheridan’s Western empire continues to evolve. Still, plenty of questions remain about what’s next for the Dutton family and the wider world they helped define.

Here are the four biggest questions keeping Yellowstone fans talking.

1. Luke Grimes Says “Nobody Wanted Yellowstone to End”

When the final season wrapped, even the cast struggled to say goodbye. Luke Grimes, who played Kayce Dutton, admitted the end was “bittersweet” for everyone involved. The show’s explosive finale left fans reeling, but Grimes is far from done with the Dutton legacy.

He’s set to reprise his role in Y: Marshals, where Kayce trades his ranch life for a U.S. Marshals badge. The new series blends the grit of Yellowstone with high-stakes law enforcement action, promising a fresh yet familiar tone for viewers who aren’t ready to leave the West behind.

2. Is 6666 Still Happening? The Spinoff Stuck in Limbo

Once touted as the next great Yellowstone saga, 6666 has hit a frustrating standstill. Centered on Jimmy Hurdstrom’s life at the legendary Four Sixes Ranch in Texas, the series was expected to bring back Jefferson White and other fan favorites.

But production delays, creative shifts, and Sheridan’s growing workload have kept the project on the back burner. Paramount remains tight-lipped, leaving fans wondering if 6666 will ever see the light of day — or if Jimmy’s story has quietly ridden off into the sunset.

3. A Guide to Yellowstone’s Expanding Frontier

From 1883 and 1923 to Y: Marshals and The Madison, the Yellowstone universe is growing into a vast storytelling landscape. The Madison, led by Michelle Pfeiffer, promises a bold new tone while staying rooted in the moral gray areas that made Yellowstone a cultural phenomenon.

Each spinoff explores a different facet of the American West — from the frontier’s early struggles to modern power dynamics. With Sheridan’s storytelling touch, fans can expect more sweeping vistas, complex loyalties, and the signature tension between family, land, and legacy.

4. Which Yellowstone Alums Are — and Aren’t — Returning for Y: Marshals?

While Luke Grimes is confirmed to return, the rest of the Yellowstone alumni roster remains uncertain. Rumors suggest appearances from Gil Birmingham (Thomas Rainwater) and Moses Brings Plenty (Mo), whose storylines could naturally connect to Kayce’s federal investigations.

However, don’t expect everyone to saddle up again. Kelly Reilly (Beth) and Cole Hauser (Rip) are both focused on their own rumored spinoff, while Kevin Costner’s future in the franchise remains unclear following his exit from the main series.

The Takeaway:
The Yellowstone universe isn’t slowing down — it’s evolving. Between Y: Marshals, the fate of 6666, and new projects pushing the boundaries of Sheridan’s storytelling, one truth remains: the Dutton legacy may change form, but it’s far from over.
