An inside source has just told us that Apple is targeting a Monday, December 13th launch of the Mac App Store. The company apparently told developers to have their software prepared for a launch as early as Monday the 6th of this month, but our contact would be shocked if that happened at this point. Apple has made no official announcements regarding this, and delays could always happen, but there's a push to be launched before Christmas, well ahead of the previously estimated January release.At the Back to the Mac even on October 20th, Steve Jobs confirmed that the Mac App Store should be launched after 90 days which means late in January 2011 so we can't verify these claims but we do know that Apple has already started asking developers to submit their apps to the Mac App Store and has already seeded a new version of Mac OS X 10.6.6 to Mac App developers. So this may claims that Apple would launch it earlier than what they said.
