Lucasfilm currently has almost a dozen Star Wars movies in development right now. These projects are helmed by Dave Filoni's Heir to the Empire, Patty Jenkins' Rogue Squadron, Jon Watts, Sharmeen Obaid-Chinoy, James Mangold's Dawn of the Jedi, and Taika Waititi, several of which are set in the New Republic era. Moreover, Donald & Stephen Glover are writting a Lando Movie, and Simon Kinberg a whole new trilogy. Notably, the films by Obaid-Chinoy, Watts and Kinberg are set to take place after The Rise of Skywalker. However, none of these movies has started production yet.
As for the new trilogy, Kinberg is set to oversee it, with Watts directing the first installment. The trilogy could also take over the stories from Obaid-Chinoy's Rey movie and Adam Driver and Steven Sodenbergh's cancelled The Hunt for Ben Solo movie. Although it is unclear what this movie was about, it can likely made to fit in with the rest. Moreover, this trilogy -what can be called the second half of Volume II of the Skywalker Saga- could then explore some of the accidental narrative threads left by the sequel trilogy. Episode I-VI could then be dubbed Volume I, as that is Anakin's story.
The new trilogy could draw inspiration from George Lucas’s original sequel trilogy plans, which centered on a new hero named Kira, Luke rebuilding the Jedi Order, and Leia establishing the New Republic. In this updated version, Rey and Poe could take over Luke and Leia’s roles. Finn knows what it's like to need a place to belong and can offer the same to others, so he'd serve as Grandmaster on a council with Cal Kestis, Grogu and Gungi. Given the timeline, Darth Krayt can replace Maul in the new trilogy. The Yuuzhon Vong from the New Jedi Order book can also feature as overarching threat.
Rey’s journey, in particular, could focus on her struggle with abandonment. In the sequel trilogy, Rey formed connections with Han, Luke, and Leia, only for each parent-figure to shift their focus to Ben Solo. Similar to how Anakin had an arc overcoming his parent-figure issues, the same can be done with Rey. Rey’s arc could begin with her and Ben having a child named Kira, born from Ben’s life-force transfer just like how Anakin was born of the Force. Struggling with abandonment herself, Rey must learn to be the parent she never had to ensure Kira doesn’t fall to the Dark Side.
The sequel trilogy introduced the Force Dyad concept, which fits with existing ideas like the Force Monad (the Chosen One) and the Force Triad. This trilogy can have Anakin explain he became the new Father, and when Ben grew in the Dark Side, he corrected this by putting Rey into the Light Side of the Triad, resulting in her natural affinity with the Force. However, Ben’s return to the Light in Episode IX disrupted this balance, leading to Rey losing her Force affinity. This would send Rey on a quest to restore her connection to the Force, which plays into her initial abandonment of Kira.
The Rise of Skywalker also introduced the Sith Eternal, who worshipped Palpatine as if he were the only true Sith. This is similar to the Rule of One, where devotees served one Dark Lord. In Legends this was Darth Krayt, another reason to use him. He could be a Sith Eternal member that rose through the ranks and now leads an underworld empire that opposes a new Galactic Alliance. Unlike the demilitarized New Republic, the Galactic Alliance would remain armed, having learned from the Rebellion and the First Order that even a small force can topple galaxy-wide governments.
However, Disney still needs to schedule their announced movies. The Mandalorian & Grogu has just released this year, and Starfighter is currently set for May 26, 2027. Although Jon Watts' involvement is the most recently reported, a release window was not given. Just like previous director or writer announcements it is unclear when or if the movie will reach the big screen, although, not all movies need theatrical releases. For example, Lando was originally a tv project, while Kathleen Kennedy already confirmed Roque Squadron has been discussed as a tv project.
Either way, Mandalorian & Grogu has just arrived, and is followed by Ahsoka. Starfighter is also confirmed to be his next movie and the next Star Wars movie to premiere. Considering the relative availability of the other directors involved, a possible release slate could look like this: Starfighter in 2027, Heir to the Empire in 2028, Jon Watt's Episode X in 2029, Dawn of the Jedi in 2030, Obaid-Chinoy's Episode XI in 2031, Taika Waititi's movie in 2032, and finally Episode XII in 2034. With Ahsoka releasing in 2027, Lando and Rogue Squadron can release in 2028 and 2029 respectively.
