Update: Later Tuesday, it was confirmed that Jobs will speak at the annual conference. Jobs will be interviewed on the opening night, June 1.
Without sources, Valleywag reported Tuesday that Jobs is expected to appear on stage at the conference, likely opposite tech columnist Walt Mossberg of the Journal and BoomTown's Kara Swisher, who co-host the conference.
"An appearance at D would not only speak to Jobs' continuing physical vitality but also his willingness to grapple with some of the thorny new controversies surrounding his company, including its newfound power over news media publishers and rival Adobe," author Ryan Tate wrote.
Swisher told Valleywag that Jobs was invited to attend, but would not comment any further. The report said that Jobs is "slotted for the show but not 100 percent confirmed." The event is scheduled for June 1-3.
After taking off a significant portion of 2009 due to illness, Jobs returned to the stage last September at Apple's annual music event to introduce new iPods. He had previously returned to work in June after receiving a liver transplant. The chief executive also formally introduced the iPad in January, and earlier this month unveiled iPhone OS 4.
Arguably the most famous moment at the D Conference came with Jobs in 2007, when he shared the stage with Microsoft's Bill Gates at the D5 conference. The two sat down together for an interview with Mossberg and Swisher, in which the tech titans praised each others' work and gave insight into their history with one another. Jobs said that Gates and Microsoft were better at forming partnerships, while Gates praised Jobs and Apple for their ability to figure out the next big thing in consumer technology.
This year's lineup includes Microsoft CEO Steve Ballmer, director James Cameron, FCC Chairman Julius Genachowski, and Facebook founder and CEO Mark Zuckerberg, among many others.
