What is Apple track record? About 2 to 5 weeks after announcement an OS goes live? Well, Lion took longer. Granted iOS 6 beta did not have much exposure, but perhaps Apple is being very careful? My predictions, OK, these are outright guesses: June 11 (today) iOS 6 Beta is expanded. As soon as June 22 it is available to all, IF they feel it is ready (long shot for sure). Based on next iPhone rumors. July 17 I think is the most likely chance of release.
