Multiple sources show that Dalíland received its general U.S. theatrical and on‑demand release on June 9, 2023.

• Wikipedia notes that Dalíland "was released in the United States on June 9, 2023" by Magnolia Pictures. (en.wikipedia.org)
• Collider reported that Dalíland "will be released in theaters and on-demand on June 9, 2023." (collider.com)
• Release-tracking sites likewise list the theater/PVOD date as June 9, 2023. (whentostream.com)

The podcast (Dec 24, 2022) prediction was that the movie would "be coming out next summer." In common U.S. usage and in the film industry, movies released in early June are part of the summer movie season, and meteorological summer in the U.S. begins on June 1. Since the film’s public release fell on June 9, 2023, this matches the prediction that it would come out in summer 2023.

Therefore, the prediction that Dalíland would be released to the public in the summer of 2023 is right.
