Thanks to developer sources, we have a potential PlayStation 3 release date. Apparently, both Japan and the U.S. will see a PS3 release date in September of 2006. This has been confirmed by launch games having release dates in September. That would make the PS3 beat the Nintendo revolution release date by a couple months.
Some in the industry have taken this as a lead to speculate that September 16 would be a release date in Japan (a Saturday before a national holiday) followed by September 21 in the U.S. Neither of these launch dates have been confirmed by Sony.
