When Apple's OS X 10.8 Mountain Lion is released next month, it won't ship with the Facebook integration announced at this year's WWDC. That's according to a banner on Apple's Mountain Lion page, which clearly states that desktop Facebook integration won't launch until "this fall." The company also mentioned this release schedule in a footnote to a press release issued Monday.

Apple spent relatively little time discussing the feature during Monday's keynote presentation, though it was included as a separate download within the "near-final" Mountain Lion Developer Preview 4, released shortly afterward. The exact motives behind the decision remain unclear, but as 9to5Mac points out, this staggered release schedule would allow Apple to simultaneously introduce Facebook integration on both Mountain Lion and iOS 6, also slated to launch this fall.
