Since it hasn't been mentioned in this thread yet:
The director is Jason Reitman, son of Ivan Reitman, who directed the original Ghostbusters (and a bunch of other great 80s comedies). Jason Reitman is best known for Thank You for Smoking (2005) and Juno (2007). I'm not really familiar with his more recent films.
They are basically retconning the 2016 Ghostbusters film and returning to the original universe. Leslie Jones is not amused:

So, it's too early to say anything for sure, but these are promising signs.
