While Apple will ship Mac OS X 10.4 "Tiger" this year, its tease campaign for Worldwide Developers Conference 2005 continues today with news of 30 more sessions to be held in June.

The company now offers details of 120 sessions on Mac OS 10.4 "Tiger" (and other topics) - it revealed 90 such sessions last week. The company has also added information on special events at the show.

Noteworthy session titles include: a graphics and media 'state of the union' address; a games development and publishing strand; and a close look at harnessing the audio (and also video) capabilities of QuickTime 7.

Special events for developers include a reception with Apple Developer Connection staff on June 6; a series of lunchtime sessions with O'Reilly publishing staff (including founder and CEO Tim O'Reilly); a session in which developers try to stump Apple's own engineers and the Apple Design Awards.
