DigiTimes reports that Apple's next generation iPad will become available in about 3-4 months. The publication's supply chain sources indicate that the next generation iPad parts are starting to ramp up while the iPad 2 production is starting to decline. OEM production of iPad 2 will remain high at 14-15 million units in the fourth quarter of 2011 but decline to 4-5 million units in the first quarter of 2012, paving the way for the launch of the new iPads, the sources noted.
