A few people have reported that Princess Twilight is already available at Build a Bear stores, along with Spike. There are a few pricing options here. If you want just the pony, you are looking at 25 bucks, with the costume is 53, and with Spike is 63. Spike on his own clocks in at 10 bucks.
Find them all over here! Thanks to everyone for the heads up! Tips are always welcome.
Update: And an image from the store from Scott!
