Who isn't interested in what the next iPhone will offer? The standard by which every other phone is measured is about to get a makeover, and while nobody really knows for sure of the extent of the changes, plenty of people are offering up suggestions. There are so many conflicting and continually updated posts on the topic that one could easily carve a full-time hobby out keeping track of them all.
Thankfully, WIRED has listed the most commonly agreed upon possibilities and rated their probability of materializing in reality. Processing power, storage, the metal strip, the glowing logo, the screen... All of it's covered and sourced. Great list.
