So maybe those ribbons can be part of it's flesh? That's a little weird, but, hey. @_@
I mean, I have no problems if it turns out to be a Ghost type, I mean, I'm a guy who enjoys Ghost types, it's just, eh, it's a little weird, thinking how it can be a ghost type, when... it doesn't look like a ghost type? But, yeah, there are those weird pokemon who are thought to be one type but are a totally different type. Yeah, but, you know, it does sort of reminds me of Driftblim in a way. It's overall anatomy and features reminds me of those.. "hands" Driftblim uses, so, yeah, I agree it can be some sort of ghost type in that way, but... eh.
Seriously, think about it. Why would they take Eeveelutions and add a Normal type? It's not super-effective against ANYTHING. By Gen. VII or VIII, and even during a Gen. VI remake, Sylveon would quickly become forgotten.

Honestly, if it does turn out to be a Normal type, I'd be lying to say that I wouldn't be disappointed, but, over the past weeks, I do see fair speculations of it being one. But, yeah, it can be anything at this point; I don't think there's a 'set' pattern for Eeveelutions.
