Some more things I noticed while watching the trailer. I'm guessing the end of the trailer with the colony being attacked by monsters happens early on, because you see footage of that in gameplay a bit earlier and everyone (sans what appears to be a guest party member?) has basic HP and no MP/EP/Whatever they're calling it.
The trailer also appears to have multiple builds, seeing as how the UI keeps changing slightly from shot to shot. Also appears to have more than just the standard weather effects, juding from the icon.
Oh yeah, the Doll Fuel indicator shows up even when you're not piloting one at times, and there's a few very brief moments where they ARE piloting one, but it doesn't drain. Huh, bizzare...
Yeah, it's a silly claim to make. Takahashi has never let down in the story department before, regardless of what your opinion is about his style shift with Xenoblade and Soma Bringer.
