Mistborn readers watching Brandon Sanderson's public progress circles finally got the update they have been refreshing for: a major Mistborn screenplay milestone in his latest Weekly Update, timed to the books' twentieth anniversary month.
This is a status post for Cosmere fans who want the Apple TV film path without Hollywood rumor math. Here is what is verified, what the tracker says today, and what still has to happen before anyone casts Vin.
The milestone, from Sanderson's channel
Sanderson's new Weekly Update is titled A Major Mistborn Milestone + Weekly Update. The video opens on a Mistborn screenplay chapter, then moves on to Gen Con and other Dragonsteel notes. Watch the primary update here:
Where the public tracker sits
Sanderson's official site still publishes live progress rings for active projects. When we checked brandonsanderson.com, the Mistborn Screenplay ring read 95%, with Ghostbloods Book 1 and Songrise 4.0 at 100% and Riftwake Book 3 lower on the board.
| Project on Sanderson's site | Progress shown |
|---|---|
| Mistborn Screenplay | 95% |
| Ghostbloods Book 1 | 100% |
| Songrise 4.0 | 100% |
| Riftwake Book 3 | 41% |
That 95% reading matters for expectations. A major milestone update can land while the public ring is still short of 100%, especially if the remaining slice is polish, notes, or turn-in packaging rather than blank pages.
