Apple is preparing to launch a slightly upgraded iPad 2 in March of 2012, DigiTimes reported on Thursday. The new iPad is rumored to be thinner and is said to offer better battery life than the current model. It is unclear what Apple will call the device launching in March, but the company reportedly has plans to launch a “real” iPad 3 during the third quarter of 2012. Samsung, Sharp and LG are said to be working on a new Retina Display for the next-generation iPad, which may also pack a faster A6 processor, but rumors of manufacturing issues have suggested it may take Apple longer than originally planned to introduce a model with that equipment. A report last month from Ticonderoga Securities suggested that Apple is planning a cheaper iPad model that will debut early next year ahead of an iPad 3, which won’t launch until the second quarter.
