Three new blister packs featuring Decidueye, Incineroar, or Primarina will be released in Japan on January 27th for 810 yen each. This is the same day the Sun & Moon Strengthening Expansion Pack mini-set will be released in stores.
Each blister will come with a holo promo of one of the Pokemon as well as a booster pack of Collection Sun, a booster pack of Collection Moon, and two booster packs of the mini-set.
No word yet if the Pokemon will be Pokemon-GX or regular Pokemon. Thanks goes to Bangiras for the translations!
