There already is. It's called: "Kirby's epic yarn"
For the Wii.
A Kirby game for the Wii has a TBA release date for Japan, but hasn't been announced for a release in the US or Europe. In short, there is one, but it's still in development.
No, it focuses on the older games.
Kirby's Epic Yarn will be scheduled to come out October 1, 2010 in the US.
Kirby and the Rainbow Curse will be released for the Wii U sometime in 2015.
As of now (Dec. 2014), a new Kirby game called Kirby and the Rainbow Curse is in development. It will be released for the Nintendo Wii U sometime in 2015.
It's just for the Wii.
There is one Kirby game for the GameCube - Kirby's Air Ride, a racing spin-off. A more traditional Kirby game was planned, but was ultimately moved to the Wii and released as Kirby's Return to Dream Land.
Nintendo has not yet announced when Kirby Wii is coming out.
Kirby's Return To Dream Land (Kirby Wii) will be released in October 24, 2011 in North America.
You need a classic controller for EVERY virtual console game.
