Rumors that a second-generation iPad mini with a Retina display is set to launch ahead of Apple’s typical annual schedule next year have been swirling, and now it appears Apple’s (AAPL) full-size iPad may be sticking to its new semiannual release schedule. According to a report from Japanese blog Makotakra that cites an anonymous “inside source,” Apple plans to launch a new thinner, lighter 9.7-inch iPad as soon as March 2013. The fourth iPad model was just released last month alongside the iPad mini, but March was also suggested in recent Retina iPad mini rumors. Makotakra states that the new iPad will adopt styling queues from the current iPad mini model, unifying the look of Apple’s larger tablet with the iPad mini and iPhone 5.
