A new classification from the Alberta Film Ratings office for "Transformers: The Last Knight (IMAX exclusive trailer)" indicates that IMAX viewers at least will get an early peak at the upcoming movie. No release date is indicated but Fantastic Beasts And Where To Find Them does seem like a prime opportunity. If not with that movie then Rogue One: A Star Wars Story is the other likely candidate for the most all ages audience the TF5 marketing group would be aiming for. The office just rated the trailer as PG and provided no additional info marketing plans or if a non-IMAX trailer are in the works.
Update: The likely IMAX "trailer" can be viewed here.
