Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Steve Jobs Discusses Health with Reporter
The issue of his health, however, was recently raised again after his appearance at WWDC 2008. While MacRumors had previously avoided speculating about this topic due to its personal nature, a New York Times article by Joe Nocera now provides first hand information from Steve Jobs, himself.
In an unusual sequence of events, the author of the article reports that Steve Jobs called him directly, and divulged details about his recent health problems but only if it was kept "off the record". In the end, Nocera does reveal that there was nothing that contradicted his previous article on Steve Jobs' health and that "while his health problems amounted to a good deal more than 'a common bug,' they weren't life-threatening and he doesn't have a recurrence of cancer."
This is likely to be the most official response about Steve Jobs' health that will be publicly disclosed.
