You sick of it yet?
My two cents on its type question is that it -may- be a shadowy promotional plan to launch a new light type. Hiding the type of a new Eeveelution, as much as launching that kind of massively awaited pokémon this early in the Gen are kind of suspicious and makes people's theories run wild. Then BAM! they would confirm the new type and everybody would love it even more, etc. But this could be totally wrong, since I also remember many awaited the light type to fall on Reshiram already. :T;;; We will see.
EDIT : Fairy type confirmed! Not light but still a new type!
