It's real even if the name is something else the trailer is old.
That's why people are suspicious... You can edit video footage. Wouldn't even be that difficult.
not only that, it looks like a personal home screener room and a sub-par projector.
it might 'look' officalish, but that is easy as hell to fake. Also, if they were doing something as major as changing the title they would announce it with a year old trailer? ya huh.
