Didn't I remember Serebii posted something on the main site that you take a picture of yourself and that indicates which Pokemon you are?
Well there you have it... Solves that problem...Edit @ 16:18: Updated the images to ALL be full sized so click the image to check the gallery. Also of note is that you don't get a quiz to pick your Pokémon, it is done via a view through the 3DS camera of the player. Exact requirements aren't known
