iOS 6 is pretty much confirmed to be a part of the keynote speech as iOS 6 posters are present all around the venue.
Another interesting announcement that could be made at this keynote is regarding the maps application in iOS, which has been using Google Maps data till now. But that might change today. Apple is set to unveil its own mapping application that will most likely replace Google Maps from iOS.
Rumours also suggest that Facebook integration in iOS might finally become a reality today. Apple already supports Twitter integration in the operating system, but there is no way to share on Facebook.
The company is also likely to announce updates for OS X Mountain Lion, iCloud and an iPad version of the voice assistant, Siri.
