What we know so far:

1. Release Date: While no date has been confirmed, estimates suggest that The Nun 3 could be released as late as 2027 or 2028. This is partly due to the pattern of Conjuring and Nun movies being released in alternation​.
2. Plot Possibilities: Based on The Nun 2, Valak (the demon nun) was seemingly exorcized, but the film hinted that a part of Valak might still reside in Maurice. If a third film is made, it would likely explore Maurice’s possession, how Valak regains strength, and possibly the Warrens’ involvement​.
3. Cast Speculation: If The Nun 3 happens, Bonnie Aarons (Valak), Jonas Bloquet (Maurice), and Taissa Farmiga (Sister Irene) are likely to return. There is also speculation that Patrick Wilson and Vera Farmiga could reprise their roles as Ed and Lorraine Warren​While fans of the franchise eagerly await confirmation, the next Conjuring movie (The Conjuring: Last Rites) is expected to be released in 2025, and more details on The Nun 3 may follow thereafter.

More about the Future of The Nun Franchise:

1. Storyline Continuation: The Nun movies are prequels in the Conjuring timeline, meaning they explore events that occurred before the Warrens became involved with Valak. In The Nun 2, we see Valak grow stronger after absorbing a holy relic, but Sister Irene manages to exorcise the demon. However, as fans of the series know, Valak reemerges in later Conjuring movies, so The Nun 3 would likely bridge this gap by showing how Valak reclaims Maurice’s body and continues its rampage​.
2. The Role of Maurice: In The Nun 2, Maurice (also known as Frenchie) was heavily involved, and it’s hinted that Valak is still connected to him. Theories suggest The Nun 3 could delve deeper into Maurice’s backstory and potentially introduce a secret organization tied to Valak’s resurgence​. Maurice’s possession may also be central to connecting the plotline with The Conjuring movies, especially since Ed and Lorraine Warren eventually meet him.
3. The Warrens’ Involvement: If The Nun 3 happens, we may see Ed and Lorraine Warren stepping in to handle the aftermath of Maurice’s possession. This would provide a direct tie-in to The Conjuring movies, bringing the timeline full circle. Fans are eager to see if Vera Farmiga and Patrick Wilson will reprise their roles as the iconic paranormal investigators​.

Franchise Success and Future Plans:

The Conjuring universe continues to expand, with The Conjuring: Last Rites expected to be the next installment in the franchise. Given the track record of previous films, it’s highly likely that The Nun 3 will follow this, as the Conjuring films have consistently explored different timelines and demonic forces. The demand for The Nun films, especially given Valak’s popularity, makes it a strong candidate for another installment​.

In summary, while we don’t have concrete details, The Nun 3 will likely focus on Maurice, Valak’s resurgence, and possibly bring in the Warrens for a dramatic confrontation. Fans of the series should keep an eye out for updates, as more information will likely follow the release of The Conjuring: Last Rites.
