I can confirm that the 3rd movie for Winx Club will the last in fact. This information was passed onto me from a Rainbow employee in the industry, the films we're planned as a trilogy and are going to be ended with the 3rd one. This does not include the rumored live-action film that will be something else completely.
What do you all think? Are you happy or sad that the 3rd film will be the last?
