Joystiq is reporting that in a recent BBC radio interview, Wil Wright stated that Spore is ‘in final testing and was ‘roughly’ six months away from release’.

From Wikipedia:
Spore is a multiplatform god game under development by Maxis and designed by Will Wright that allows a player to control the evolution of a species from its existence as a multicellular organism to a spacefaring sapient creature. The game has drawn wide attention for its massive scope, and its promise to simulate this development of a species through open-ended gameplay using procedural generation.
