Maximo: Ghosts to Glory is, according to Capcom, not a sequel to the Ghosts and Goblins or Gouls and Ghosts series, but rather a homage to those great games. Unfortunately, Capcom will only bring this 3D action game to PS2. However, we might see a GameCube version after all some day.

In the last EGM, there was an article about Maximo.
In the 2nd paragraph of this article, an interesting passage reveals the interest of Nintendo towards this play. Nintendo would have even already contacted Capcom to ask for a conversion of Maximo to GameCube.

"Capcom is mulling over bringing Maximo to other platforms. When we point out to producer Mark Rogers that the game's all-ages appeal would fit well on the GameCube, he says, "You're not the first person to say that. A few people from Nintendo have said that, too."

So there you have it. Capcom knows that we want this game, and perhaps they realize that bringing it to GameCube would be a good thing.
