Several manuals for the upcoming Mac OS X 10.7 Lion have been spotted by 9to5 Mac on the Amazon.UK website
and all are set to be released sometime around late July, hinting that the OS will also launch around that time. WWDC is expected to be from July 5 to July 9 and it would make sense for Lion to be released shortly after WWDC as these manuals seem to suggest.
Whilst the release date of these guidebooks don’t confirm a late July launch it makes a late July launch likely because there have been several previous cases of Amazon guidebooks effectively revealing a products launch date, such as Office 2011 last year.
Some of the manual covers include references to the already known features of Launchpad, Mission Control and changes to the dock, all of which were revealed in the ‘Back to the Mac’ event late last year.
