I'm not a bandwagoner when I say this, but Super Mario Galaxy 3. Ever since the sequel came out, I've wanted more. That game was truly fun and I want more of it. I've also been wanting a Zombie Highway 2 recently, there's a lot that could be added/improved in Zombie Highway.
Battlefront 3 ^ Oh look, it has been mentioned I too wound like to see a Battlefront 3 but I heard Disney is ruining it for everyone cause they are firing developers or something. Not sure if true though...
Always wanted to see a sequel to Eternal Darkness. Nintendo keeps teasing by constantly renewing the trademark.
