"At Nintendo’s conference in Japan, they announced the “Wii de Asobu” selection (a.k.a. “Let’s Play on Wii”). These titles are GameCube games that have been re-made with Wii controls. The titles announced for Japan were Donkey Kong Jungle Beat, Pikmin, Pikmin 2, Metroid Prime, Metroid Prime 2: Echoes, Mario Power Tennis, and Chibi Robo. Many, including me, hoped that these titles would come to the US and now we have proof that they may indeed be coming stateside.
Pikmin and Pikmin 2 have been rated by the ESRB again, and they both now include the Wii tag, confirming that they’re coming to the US and for Wii. On top of that, Amazon has a listing for Pikmin for Wii now. Games4Gamers has listings up for Mario Power Tennis and Pikmin, both with a release date of 2/9/09. While the release date isn’t confirmed, it’s good to know that these titles will be coming to the US. I held off on buying Pikmin and Pikmin 2 for some stupid reason and I’m happy I did that so I can get them for Wii. And if you’re wondering, the picture above is a translation of a slide from Nintendo’s conference."
