[video=youtube;KDnKuFtdc7A]https://www.youtube.com/watch?v=KDnKuFtdc7A[/video] Arial battle with Rodan! Good time to invest in some construction companies too....
Ditto - we've got four monsters in this movie; I want to see them fighting and destroying buildings! I doubt any human plot-line they throw in there is going to entertain me as much as kaiju (or "titan," apparently) carnage.
Possibly six. In the trailer, there's a thing with what looks a lot like bug-legs coming out of the ground. It doesn't seem to match the big four we know. Speculation is that it is Kumonga, a big spider-thing from the classic movies.
And there's an odd shot of a hilltop moving. It isn't quite like what you'd expect from one of the other monsters appearing (and why would you give double-shot of one, but not the others?). I have seen speculation that it is Angurius, the second ever kaiju (the monster that fought Godzilla in the second Godzilla movie).
I mean, that's making it an ensemble cast right there...
