Apple released part of the agenda of the forthcoming WWDC sessions. Most of them will be dedicated to the iPhone OS 3.0 to provide answers to numerous developers rushing to get applications available on this platform. Some sessions are specifically dedicated to specific functions, such as the one dealing with the new copy/paste feature. Snow Leopard is currently not officially presented even though 3 sessions are dedicated to Open CL. Of course things might evolve and change till June, and Apple should distribute a beta version of Snow Leopard. For addition information: http://developer.apple.com/wwdc/sessions
