The jackets of the latest volumes of Full Metal Panic! Sigma have announced that there is a new FMP spin-off in the works scheduled for this summer. The project is set to coincide with the publishing of a collection of Full Metal Panic! short stories.
Unlike most spin-offs however, the series will maintain the continuity of the story line and take place 10 years after the events of the original light novel series. The series will be drafted and supervised by original author, Shouji Gatoh, but written by Naoto Oguro.
Last June Tokyopop announced that they would publish the fourth and fifth volumes in the original FMP light novel series, however they've only shipped 2 volumes before announcing they'd be halting North American operations.
