Apple has posted the complete conference schedule for the upcoming 2008 Worldwide Developers Conference. With a very slick web-based interface all the sessions and labs are broken down by topic (iPhone, Mac, iPhone and Mac, and IT) for each morning and afternoon of the conference (though, Apple, where are the iCal calendars?).
By the looks of it, Apple seems pretty serious about this whole two bridges thing. In any case, if you're lucky enough to be headed to San Francisco you can fine tune your plan of attack and agonize over your choices at the schedule website.
