Fantasy author Brandon Sanderson recently shared progress on the upcoming Mistborn Era 3, titled Ghostbloods. While a new Apple TV+ film deal has shifted his focus, he remains committed to his established writing timeline.
The Apple TV+ script shift and the December 2026 deadline
Sanderson has recently balanced his literary output with the demands of Hollywood. As reported by the source, the author spent a significant portion of his time writing the first draft of a Mistborn movie script, which he completed at the end of July. This diversion was a known factor in his recent schedule, as he had previously confirmed in a February 2026 update that the Apple TV+ deal would impact his workflow.
Despite this, Sanderson is making steady progress on the prose itself. He reportedly finished the first draft of the first Ghostbloods book in January 2026 and is currently 10% of the way through the second draft. According to an update on his YouTube channel, he intends to have the entire book fully revised and ready for his team by late August or early September. He has set a firm deadline to turn in the final draft by December 2026, which is two years ahead of the anticipated publication date.
Avoiding the George R.R. Martin "White Whale" trap
The involvement of major studios often triggers anxiety among dedicated fanbases. The source draws a sharp comparison to George R .R. Martin, whose struggle to complete The Winds of Winter has become a legendary example of production delays. In this analogy, Martin is described as "Captain Ahab," chasing a "white whale" that keeps him from finishing his primary series, A Song of Ice and Fire.
Sanderson, however, maintains a reputation for extreme consistency and reliability. While fans often worry that Hollywood's influence can derail an author's momentum, Sanderson's ability to hit his December 2026 target—even while managing a script—suggests he is successfully navigating the pressures that have hindered other fantasy giants.
A December 2028 release for the Ghostbloods trilogy
The long-term roadmap for the Mistborn series remains ambitious. Sanderson plans to follow the same successful pattern he used for the original Mistborn era : writing all three books in the trilogy before the first one is even released to the public. This strategy ensures a cohesive narrative and a steady stream of content for the Cosmere universe.
Based on the "State of the Sanderson 2025" projections, readers should expect the first Ghostbloods book to arrive in December 2028. This timeline accounts for the slower pace of traditional publishing, allowing Sanderson the freedom to manage his own release schedule while maintaining high quality.
Uncertainties surrounding the Stormlight Archive TV production
While the Mistborn schedule appears robust, several questions remain regarding Sanderson's total workload. the source notes that in addition to the Mistborn film and its potential sequels, Sanderson is also preparing for a future The Stormlight Archive television show with Apple TV+.
It is currently unknown how these secondary television projects might impact his ability to maintain his current writing velocity. Furthermore, while the progress on the first Ghostbloods book is clear, the specific title for the volume has not yet been revealed to the public.. whether the author can continue to prioritize his readers while managing multiple high-stakes Hollywood franchises remains the primary point of interest for the Cosmere comumnity.
