Technically its still alive.
Homebrew is keeping it so.
And it had a new game out last year
If I'm still correct since the last time I looked it up, the last 3 Games made (or being made) for Wii are Mario Party 9, Fortune Street, and Zumba Dance 2. I think the 4th newest is Kirby's Return to Dreamland, with the giganto Sword Kirby, as I call it anyways, and the 4 player Co-op (Kirby, MetaKnight, King DeDeDe and 1 of his Minions)
