Remember this story? Well, you should, since it's still on the front page! We might possibly know what this Wii game is now. Nintendo is supposed to have scheduled for a conference in Japan, and a list of what they'll be revealing and/or showing off has apparently leaked. While this list is unconfirmed, the source is reliable.
12月03日発売■：Wii「ニュースーパーマリオブラザーズWii」(New Super Mario Bros. Wii)
12月03日発売■：Wii「Wiiリモコンao」(Wii Remote Blue)
12月03日発売■：Wii「Wiiリモコンpink」(Wii Remote Pink)
12月05日発売■：Wii「ポケパークWii ピカチュウの大冒険」(PokéPark Wii Pikachu's Great Adventure)
12月17日発売■：Wii「NHK紅白クイズ合戦」(NHK Red/White Quiz Battle)
The fourth one there is "PokéPark Wii Pikachu's Great Adventure". Could this be the Wii title that Tsunekazu Ishihara was talking about? Now, since that release date seems incredibly close (December 5th), saying that this would be WiiWare seems like the right move.
Update: Likely Confirmed, Wii Title and not WiiWare?
As found by GoNintendo recently, Amazon has put up a page for this exact title, probably meaning that this game does exist. An interesting thing to note is the fact that Amazon is selling the product, and as such has it listed as a full Wii title. Expect more information later.
