I doubt it...but this could go along with the hiding of the type.
I am in the group that think it is a new type due to the fact that it isn't immediately guaranteed a type upon appearance and that any current type would be underwhelming since they hid it.
If this were the shiny form, it would make it harder to guess the type. You can guess every Eeveelution immediately by color...Blue, Yellow, Red, Purple, Black, Green, Light Blue. Whereas their shiny forms are a bit different...or a lot different in the case of Espeon. It is bright green.
So, who knows. Hopefully Nintedo of America reveals it tomorrow. I hate guessing and I hate surprises.
