Reggie said at last E3 that the Mario-team were hard at work. Of course, it doesn't mean they're making a new Mario-game, just a new game (though it's fair to assume it's a new Mario-game). Also:
"In the 1,000th issue of Famitsu, Miyamoto stated his interest in making a sequel to Super Mario Galaxy. Producer Koizumi said in a GameSpot interview that there is a "really high chance" several power-ups and suits that did not make it into Super Mario Galaxy would be used in the sequel."
