Reports are that the iPad 3 is currently being prepped for release in March 2012. Reports are that it will have a QXGA display and longer battery life compared to the iPad 2, though other wise be very similar; still it is expected the iPad 2 will see a price reduction to $399 when its successor releases.

Furthermore, it is expected that a 9.7-inch iPad 4 will release in October 2012 with much more powerful hardware and integrated applications. All of these strategies will look to counter cheaper tablets, such as the Kindle Fire, and more top-flight tablets from Microsoft and Google.
