I don't think it will be dragon type, that just seems like a really big stretch. It doesn't resemble anything close to any form of dragon and its has like ribbons and stuff. It'd be cool if it was I guess, but I think it's unlikely.
From my first time seeing it, those creepy eyes made me instantly think maybe it's a Ghost type, which I still think it is and my other guess is maybe they gave eevee a Normal-type evolution that involves leveling instead of a stone.
