Gamecube Software Support Waning?

Thanks to Shacknews for pointing to a CNET News report discussing the declining amount of titles being planned or released for the Nintendo Gamecube. It quotes an Activision spokesman as saying "I think it's good for the industry as a whole if you have three strong players, but that's not the direction it's going." Is the Gamecube third-party software support on its way out?
