The recent CoroCoro Leak has revealed what appears to be the "full" title for the upcoming 16th Pokemon movie, following the trend of past films in only giving partial title information initially. The title is now known to be
Extremespeed Genesect and the Reawakening of Mewtwo. It has already been previously revealed that the film's story will follow from the group of Genesect introduced in the
Episode N anime arc, and so it stands to reason that the conflict between Team Rocket and Team Plasma (originally cancelled due to Japanese earthquake) will be brought to the forefront as part of the movie's premise. This movie will be Mewtwo's first anime appearance since the 2000 film "Mewtwo Returns", so how the producers will take advantage of the improved animation capabilities now at their disposal remains to be seen.
