They probably put it in Silhouettes because they are naive enough to think that English Fans or at least the young children that play the game aren't aware of the new pokemon expect the ones on the English BW site.Interesting they've put them as silhouettes, as if it's going to be some big reveal. :\ Either way, I'll be glad I can finally refer to them with a name that I don't have to copy and paste from somewhere. :P
Mijumaru better have a cute name, or I might be put off.

...aaah, who am I kidding? Mijumaru I will choose you! ^^
