Mac Rumors posted a news story that Digitimes claims that Apple has canceled its iPad 3 supply schedule for the second half of 2011, which means the iPad 3 won't be launching until 2012

Apple was originally set to launch its iPad 3 in the second half of 2011 with a supply volume of 1.5-2 million units in the third quarter and 5-6 million in the fourth quarter, but Apple's supply chain partners have recently discovered that the related figures have all already been deleted, the sources pointed out.Sources seem to believe that poor yields of the new 9.7" 2,048 by 1,536 pixel Retina display are the reason for the delay.
