The promotional materials continue to emphasize the fact that this year's conference is focused primarily on the iPhone OS, which powers the iPhone, iPod touch and iPad.
Steve Jobs will probably kick off the keynote with an update on the state of sales of the iPad and iPhone OS - 2.5 million iPads and 90 million units of the iPhone, iPod touch.
iPhone OS 4, which Jobs previewed in April - several demos of the new features such as background audio, background location, iBooks, folders for organizing apps, VoIP calls, quick switching between apps, and possibly even the social network for games .
New Facebook integration into iPhone OS. Syncing iPhone contacts with Facebook contacts. Upload iPhone photos and video directly to Facebook.
Apple's iAds. Steve Jobs will likely be rolling out iAds during the keynote, announcing early advertisers and app partners.
MobileMe - perhaps free "lite" access?
New iPhone :
Speculations abound on what Steve will be announcing in his keynote. The most obvious will be the new iPhone. The name of the new device is probably to be called the iPhone HD. Pursuitist also notes that the device will be offered in all white and all black, although the Moscone photo appears to show the phone in a rainbow of colors. Other features include a front-facing camera with video chat and an upgrade to iChat, better battery life, a camera with higher resolution (and a flash), and advanced apps management and multitasking with iPhone OS 4.0.
One picture snapped through the windows of the building shows a banner centered around folders, a new feature in Apple's soon-to-be-released iPhone OS 4. It shows the applications Air Sharing, Bento and Evernote in an automatically named "Productivity" folder. The banner reads "Drag. Drop. Organize."
