Is Gogeta super saiyan blue confirmed in the new Dragon Ball Super movie? There are many people talking about not only that they think Gogeta will appear in the new movie, but they are refering to a supposed tweet where a japanese animator said he's going to do Gogeta in the new movie. Does anyone know if this official? Supposedly the official release of this info was done in japanese. Any translation?
Gogeta Blue hasn't been "confirmed" to appear in the DBS movie. However, it seems very likely that it might be the case. An animator Yoshihiko  Umakoshi, mentioned on a live NikoNiko broadcast that he was practicing Gogeta. While the above mentioned information is accurate, it has to be noted that Umakoshi's names isn't on the film credits. However, not all the animators working for the Dragon Ball Super movie have been named.When the new DLC (Extra Pack 3), was released for Xenoverse 2, on further Datamining, there was one character who had Super Mad Dance as a super and the Vanisher Guard evasive which are Gogeta's moves. Another character had the Gigantic Meteor Ultimate who is implied to be Broly. Hence, Gogeta Blue and Broly are being predicted to be the new characters that get released in Extra Pack 4, after the movie.Further information with regard to the animator and his comments can be read here.
