Some people may be under the false belief that the new iPhone 4s is just an "update". But when you spend some time with the new SIRI voice-command features, noticeably snapper speed flipping between apps and the new 8-megapixel camera with 1080p video...you start the get the full picture. This is not a new strategy for Apple. If you look at the Macbook Pro line of Apple laptops you will note that the overall look has not changed for many years but the product offering inside has. Most likely this is the road Apple is interested in pursuing with their iPhones as well.
That is not to say that they won't come out with a new configuration but from an operational efficiency standpoint, Apple will try to leverage the form-factor as long as it competitively can.
To demonstrate some of the video prowess of the iPhone 4S, Benjamin Dowie has shot some incredible footage to really highlight the smart-device's 1080p video capabilities. Benjamin is a professional videographer and was really impressed with the depth of field found in a smartphone's camera. He did tweak the colors while editing the footage in Final Cut (Apple's professional video editing) software.
