In a shocking turn of events, IDG World Expo officially announced today that Steve Jobs will in fact headline next year’s MacWorld San Francisco conference, with his opening keynote address set to go down at 9:00AM sharp on January 15th. Exactly what that keynote will entail remains a mystery, of course, although we’ve certainly heard plenty of rumblings on the matter. Whatever it is El-Jobso has in store, you can be sure we’ll have by-the-minute coverage of it, so mark your calenders and watch this space, or not.
