Apple today announced that it will be showing the next major revision of Mac OS X, code named “Panther,” at this year’s 2003 Worldwide Developers Conference. Originally scheduled for May 19-23 in San Jose, the conference will now be held June 23-27 at San Francisco’s Moscone Center in order to provide developers with a more complete preview release of Panther. “Our annual Worldwide Developers Conference provides our developers an in-depth look at the future of the Mac platform, and giving everyone a preview release of Panther is the best way to do that,” said Ron Okamoto, Apple’s vice president of Worldwide Developer Relations. “Moving to June ensures that every developer will leave the event with a copy of Panther in their hands.” The Early Bird registration discount scheduled to end on April 18, 2003 has been extended to May 23, 2003.
