Based on what I had seen on Kotaku, that new Wii is like the new PSP. It'll be a Euro thing only so I wouldn't worry about losing GC ports and compatibility just yet.
According to the site, 0_0, that game is in the Gamestop located on my work route (Encinitas, CA). Are you looking for a complete version of the game (disc, instructions, box) or just the game itself?
