Did anyone ever figure out the "spoilers" in the Zodiark/Hydaelyn artwork?

[Enkidoh]

The logo for the expansion isn't Ultima Thule at all, but is in fact the Moon - this is proven by the title screen outright showing the Moon looming over Hydaelyn which then literally turns into the logo - if SE wanted to hint at Ultima Thule they would have done so. And having the Ragnarok appear in the logo still fits because the ship's original purpose was to act as a shuttle moving people and supplies from the surface to the Moon as part of the Great Exodus.

Even without the title screen animation the logo on it's own all but says it's the Moon with that big black crater being clearly the Cradle of Darkness where Zodiark is/was imprisoned. Not to mention SE talked up the Moon's importance in the story long before the expansion was released, and the Moon being the logo all but underlines that.

And I can't see any bluebirds in the Hydaelyn/Zodiark artwork - Hydaelyn seems to have a crystal crown on her head, and the closest to a 'bird' that can be seen is actually parts of her staff she's holding. Ironically enough, Amano often fills his the borders of his artwork with birds and flying creatures which are there purely for visual interest and have no actual deeper connection to the subject matter, so even if there was a bluebird in there, I wouldn't take it as a hint foreshadowing Meteion.

EDIT: Annnnd.. looking very closely at said art part of Hydaelyn's crown does seem to resemble a beak poking through her hair, but... that really is stretching things, and, again I'm liable to just regard that as just part of her crown. As I mentioned Amano loves putting nondescript animals and creatures in his artwork around the borders so even if there was a bird in there, don't take it to mean "that's Meteion!", and just Amano's artistic embelishments again.
