The current MacBook Pros, iMacs and Mac Minis too are old enough from previous versions that new models of these could be announced. And, of course, a retina iPad mini is possible too.
So, I predict some kind of a multi lens multi sensor 'super-resolution' camera which combines the output of multiple cameras to increase dynamic range and resolution. And multiple cameras also help in image stabilization and leveling. If not multiple cameras, the new iPhone will probably have vastly improved image processing.
