It's 90% certain that the coming 5S will look similar to 5, based on recently leaked photos. Hence, the only changes we will probably see are hardware upgrades, which are rumoured to be: 1. Faster A7 chip, faster GPU 2. 1.5-2GB RAM to accompany numerous new features in iOS 7 3. X2 resolution (which results in 461 ppi) 4. 13MP camera with dual flash 5. Fingerprint scanning (some people speculate 'S' in this version refers to 'Security') 6. Wifi ac and LTEa 7. The new MacBook Air line has received a huge battery life upgrade, so some people hope the same thing will happen on the iPhone 5S Let's see how many of us will upgrade to 5S . Count me in as one, currently owning a 5 (without a contract).
