Augmenting the already revealed Donkey Kong: Jungle Beat and Pikmin, five other titles have been announced. http://www.nintendoworldreport.com/newsArt.cfm?artid=16843 During Nintendo's presentation in Japan at the start of their Fall Media Summit, Nintendo President Satoru Iwata announced that a handful of GameCube games would be receiving a Wii update. The re-released games are also now confirmed to have updated controls to work with the Wii Remote (and Nunchuk).
Two of those titles have already been revealed as Pikmin and Donkey Kong: Jungle Beat. IGN has further investigated to find the full lineup of titles, which includes Pikmin 2, Chibi-Robo!, Mario Power Tennis, Metroid Prime, and Metroid Prime 2: Echoes.
Furthermore, Donkey Kong: Jungle Beat will be released in Japan on December 11, followed by Pikmin on December 25. Pikmin will retail for 3,800 yen ($36), which is 2,000 yen ($19) less than a typical first-party Wii release in Japan.
There is currently no word on release of the selected Wii remakes outside of Japan.
