Well, the Wall Street Journal's headline certainly isn't going to surprise you -- Apple Developing New iPad -- that has been a safe assumption since the iPad 2 was announced. Rumors are circulating though (some, for quite a while) that are painting an increasingly convincing picture of a Retina Display-equipped slate shipping in early 2012. Reports are in that suppliers have already received Q4 orders for parts that may eventually find their way into Apple's next tablet. Can we say for certain that the iPad 3will hit shelves in Q1 of next year sporting a 2048 x 1536 screen? No, but it's starting to look more and more likely.
