Yeah, Dreddz brings up a good point. They can't exactly expand upon the gameplay introduced in the originals using the Wii's technology, and if they do use their gameplay styles as reference, then it'll probably look extremely outdated. The New Kid Icarus will have to be an entirely different adventure. Maybe, they'll use the Kid Icarus name to fill in a genre they think they're missing on the Wii, and use games of that genre as basis, rather than Kid Icarus.

Edit: There were 2 Star Fox games on the GCN, actually. The first was just the cancelled game Dinosaur Planet but with Star Fox Characters, but the second was more true to the series. But, not many people were fond of the land missions, and the air missions were apparently few in number.
