I'm still crossing my fingers for a finch.
Actually, I'm curious about who the first gym leader will be. I know that it's kind of random, but I'm hoping they do something like they did for B/W, but more refined. Actually, what I think would be neat is if the first gym leader had your starter, the rodent, the bird, and any other early route Pokemon. Not only would it be a bit of a challenge to fight that many, but it would be kind of cool to have a first gym leader with a full team. It would also be interesting to have to face off against your own Pokemon.
They better not do a rock type first gym leader though. It's getting old.
