According to an iLounge article, Apple will launch the "iPad 3" in March 2012. The new iPad will be 0.7mm thicker than the iPad2 due to the dual light-bar system for the improved screen.
A summer launch is planned for the "iPhone5", which will feature a 4" display (up from 3.5" currently) and will be 8mm longer.
A March 2012 launch could be expected of the ultra-thin 15" Mac notebook line.
