^Presumably nothing came of it, much like that Gamera concept trailer. I'm guessing Tsuburaya wasn't getting the traffic on that trailer like they wanted.
...So, my next question is: are we getting Shiro Sagisu back to score the film, too? I mean, I bet he'd do a great job scoring Ultraman; but between
Evangelion,
Shin Godzilla, and
SSSS GRIDMAN, I feel like he kind of already has.
