MightyJaxx has revealed a brand new series of Kwistal ponies with these Gala dress versions based on the season 1 finale outfits. According to their announcement, they arrive on the 31st of May, at least according to the Taobao post. There's a good chance they will have a different date for the rest of the world. There is also a variant of Rarity with a different colored dress.
Thanks to Double Dove for the heads up.
