For families, there can be more smartphones and tablets in the house than there are wall sockets for charging, let alone cables to charge them with. Apple could include a charging loop to allow users to place their handheld devices on a mat, which would wirelessly charge their devices.
There are no widely available smartphones with wireless inductive charging that are currently on the market. Apple could set a precedence with the iPhone 5 and make it not only one of the most powerful devices on the market, but also one of the most user friendly and 'simple' devices. An electronics utopia exists where we simply place our smartphones down and they charge without any wires.
With this, however, it would cause a further knock-on effect to its third-party accessory makers which could render not only their products mostly useless, but Apple's own range of docking and charging products useless. With this, it's entirely possible if Apple wants to do it, but unlikely.

Many phones offer 10+ megapixels in their back-facing smartphones. Many offer front-facing cameras to support third-party applications like Skype and other video-conferencing services. With so many using their iPhones and iPads as alternatives to traditional cameras and DSLRs for ease of use and simplicity, Apple need to pander to the wishes of the photo taking collective and boost at least its back-facing camera to 10+ megapixels.
Apple already has to stretch its resources with the limited depth of the iPhone, just over a third of an inch. It would be difficult, but not an entirely out of the question request for a boost in resolution for image capture.
