As of right now there is no release date set for the Van Helsing movie, but if The Mummy does well next year, expect Universal to make several official announcements in regards to these monster movies.
He is currently writing a new Van Helsing movie and during the course of the interview, it was revealed that the movie will be part of Universal’s monster movie universe.
Universal is really dedicated to their shared monster movie universe, which will start with the Tom Cruise reboot of The Mummy next year.
As he mentions, things can definitely change but for the moment, Van Helsing will tie into this new batch of monster movies.
