From the paintings on the wall we can figure out the main theme of WWDC 2011 are: Mac OS X Lion, iOS 5, iCloud.
The iCloud icons everywhere obviously show Apple attaches real importance to iCloud this time.
Will the iPhone 5 show up next week together with the annoucement with iOS 5? Athough rumors said iPhone 4S will attend WWDC 2011 on June 6, will it be true?
