Kirby: Triple Deluxe mini-games as standalone downloadables in Japan, including the Smash Bros-like Kirby Fighters Z. The eShop sucks in the multiplayer fighter along with rhythm platformer DeDeDe's Drum Dash on July 23, priced 750 yen each (around $7.38.) It's not known if Nintendo will spit them out onto Western 3DS systems.
A Nintendo of Europe spokesperson told Joystiq "nothing has been announced for Europe to date so there's nothing further we can share at the current time."
