No product sightings or leaks yet but renders are coming out. Some people are expecting a slimmer body, 4.8-inch screen, 8 megapixel camera, optical image stabilization, and the same TouchID fingerprint sensor.
The concept phone is shown in a video below. It reminds me of the current-gen iPod touch.
What can you say about this concept iPhone 6?
