The highlight of the invitation-only event is expected to be a next-generation iPad that is lighter and thinner than the current model, with an improved camera, and which runs Apple's new 64-bit A7 processor, people familiar with Apple's plan told AllThingsD.
Apple is expected to introduce a new version of the iPad Mini with a high-resolution Retina, also running the A7 chip.
