The Tohan book distributor's e-hon website lists the next full-length volume of Shoji Gatoh's Full Metal Panic! high school action comedy light novel series with a July 17 release date in Japan. However, it also lists the volume's full title as Full Metal Panic! 11: Zutto, Stand By Me (Jō) (Full Metal Panic! 11: Always, Stand by Me Part I).

Gatoh had written in a January blog entry that he was writing the final full-length novel volume with an eye towards a tentative spring release. He has since written an May 14 entry to apologize for not getting the book ready for spring, but added that a release date has been set. He no longer states that the next book is the final volume.
