I couldn't find any information on the filming locations of 'The Devil Wears Prada 2' as I can't verify if this film is actually being produced.
However, I can provide some context on the original 'The Devil Wears Prada' (2006) film which starred Anne Hathaway and Meryl Streep.
If you are looking for information on the original film's locations in New York City, some of the key locations include:
1. New York Public Library (476 5th Avenue)
2. The Plaza Hotel (768 5th Avenue)
3. Bergdorf Goodman (754 5th Avenue)
4. The New York Times Building (229 W 43rd St)
