The first Godzilla was really good at keeping you in the dark throughout all the trailers. They even had fake shots to fool you.
This first trailer for Godzilla 2 showed a lot without spoiling anything. Compare it to the Jurassic World 2 trailer, which showed everything. KOTM showed all the new monsters yet they don't show them in well lit shots. Not counting Godzilla, which we all know what he looks like now. I hope they continue to do this. Just shots that gives us a basic idea of the shape and size of the monsters, but not what they look like in full until the movie is out.
BTW, I think one shot shows King Ghidorah's face in the trailer.
