The Devil Wears Prada is a film released in 2006, starring Anne Hathaway and Meryl Streep. However, I found that a sequel was in development.
The Devil Wears Prada 2 is currently in development, but there have been no official release dates announced. In 2015, it was reported that a sequel was in development with Paul Feig set to direct, but nothing has been confirmed since.
More recently, there have been reports of a TV series revival of The Devil Wears Prada, but not necessarily a direct sequel to the film. However, I was unable to find any reliable sources confirming the release of a sequel film.
Keep in mind that information might change over time.
