The Wonderbolts costumes from Testing "1..2...3..." are apparently going to be a future lineup of brushable figures if these two figure leaks are hinting at anything. Flutterbutt and Ponk are decked out in their costumes from the episode. I'm guessing this will follow the same store exclusive as the gothic ponies or Power Ponies from a while back, but we don't have any kind of confirmation.
I'm looking forward to Twilight's Commander Easyglider.
