TTFC had revealed that they will be announcing a 'Big Surprise' on July 4th. They have also hinted that it won't be Kamen Rider & Super Sentai by saying 'TTFC is not only Kamen Rider & Super Sentai'.
Though it is not yet known which franchise it could be. But after Kamen Rider, Super Sentai the only thing that comes to our mind is Metal Hero. Could it be a new adaptation on the Space Sheriff?, Sequel to Space Squad series? What series or Hero will it be? Let's wait for the announcement.
