Interesting read over at KoKuGamer.com. It references this article, where apparently former baseball player Curt Schilling is making an MMO with a cost of 50-100 million.

The game is called "Copernicus", and here are some early screenshots. Here's the website for the game (Well, early product page on 38studios.com), and it's description:

Copernicus is the codename for an unparalleled MMOG entertainment experience set in a truly evolving fantasy world that is both warmly familiar and intriguingly unique. Creative giants R. A. Salvatore and Todd McFarlane, together with the design teams in Maynard and Baltimore, are crafting a story of epic conflict and heroic individual journeys in which the players’ actions will impact the fate of the world. This storyline rests upon a solid design core that incorporates the best play and social experiences available to players at launch. Driven by the creative talents of Salvatore and McFarlane and enriched through an array of products that will allow broad and deep exploration of the vast universe of Copernicus, 38 Studios is combining the ages-old art of the story with 21st century interactive entertainment.
