Comic Con is going to have some pony exclusive merch, the above "brick" being one. There are a couple others, like Fluttershy and Rainbow Dash, but Pinkie's the only one that doesn't look really off.
Books a Million are now selling Pony magnets, the cream of the crop being the cool looking Future Twilight.. Good lucking finding a Books a Million though, the ones around here have all closed down. :(
And finally if you look near the top, you can see some awesome looking key-chains. I currently rotate between a crystal Pinkie and Crystal Rainbow Dash key-chains, and they're one of the best ways to be a Brony and take ponies everywhere you go. My mouth is watering over these new key-chains. It's a German store that's making these, so I can only hope that they'll somehow become available in America.
.......I want that Twilight so bad it hurts.
