It would appear that this change has taken place earlier than previously, because the fact that God Particle was a new Cloverfield movie was already leaked.
Of course, if 10 Cloverfield Lane is any indication, the movie probably will not actually be called Cloverfield 3.
It was suggested last month by The Wrap that God Particle which J.J. Abrams had picked up to produce a few years ago, just as he did The Cellar, was being set up as a new Cloverfield film.
