There has been a rumor of a NiGHTS 2 on the Wii for awhile, but no confirmation.
I personally am hoping for at least NiGHTS 1 on the virtual console.
And to Shawn: NiGHTS was one of Sonic Teams earlier games, it took place in a kind of "Land of Dreams" place. You played as one of two human kids, your goal was to find a shrine where you would be possesed by (And essentially become) NiGHTs for a limited amount of time. You then had to fly around collecting some Blue Chips, and get to a capsule that would be destroyed by a certain amount of these chips.
Throughout the game, there was a very Chao-Like minigame with the Mepians, and you defeated enemies by flying circles around them.
