I was about to ask about the wings, because you can't really tell from the video, but then translated the artist's commentary.
Anyways, if she actually ends up with wings (6 no less), then it's highly likely she's a Metatron-Pseudo-Servant. At least her third ascension, that is. Could see them have her be regular Jeanne for the first two ascensions. But only time will tell.
I'd wait with celebrations until we get to see and hear more of the remake and the "revamped localisation". Falcom is not the same as it was two decades ago, and they don't work with people like Xseed, who actually gave a damn about their games, anymore.
