Though Apple had never made public its intention to release a third-generation iPad model this year, a new report claims the 2011 launch of the iPad 3 has been canceled. It has been widely reported that Apple intended to launch a new iPad model with a Retina Display this year, however DigiTimes on Tuesday claims Apple has canceled those plans due to display issues. The trade paper’s unnamed sources from within Apple’s supply chain believe the reason for the delay lies in the inability of Apple’s display partners — Sharp, LG and Samsung — to manufacture high-resolution 9.7-inch Retina Display panels quickly enough. DigiTimes says that Apple plans to have between 28 and 30 million iPad 2 units built in the second half of 2011 in lieu of an iPad 3. A report from TiPb late last week claimed Apple would launch its iPhone 5 in October and the iPad 3 would not launch until spring 2012.
