Check out this interview with Dean DeBlois on the making of How to Train Your Dragon 2 and his ideas for How to Train Your Dragon 3! He also talks about how changes in the story and roles of Valka and Dragon in Dragons 2 have changed the future of the franchise.
Work on the screenplay for the third film will continue until the end of the year. And, unfortunately, he again confirms that the third film will tell a story of why dragons no longer exist. But perhaps we can still expect dragon-related spin-offs in the future!
Thanks, DragonBassist!
