The special editions come in 2 designs: one in yellow featuring series mascot Pikachu, and one in black featuring the new Legendary Pokemon, Solgaleo and Lunala. Both versions retail for 20,304 yen (or $199 USD).
In addition, a special double pack featuring both Pokemon Sun and Moon will be available at launch, featuring what appears to be physical copies of both games. The pack comes with a download code for 100 Poke Balls.
It is currently unknown if any of these bundles will hit North America. Pokemon Sun and Pokemon Moon release worldwide on November 18th.
