If those notions don't get you excited, you're not alone. The difference between the iPhone 5 and 6 was negligible apart from the screen size and you would be justified in expecting something of revelation this time around.
So far, the most excitement will probably be generated by the new home button which will be a touch-sensitive surface flush with the screen, instead of a physical indent. Apple's Force Touch technology will provide haptic feedback when pressed, much like the Force Touch trackpad on Apple's most recent MacBooks.
Of course there will be internal performance upgrades but respected Japanese blog Mac Otakara says the iPhone 7's design will appear a bit too familiar on the outside.
It notes the only external switches will be: "its proximity sensor on the front changed to the dual specification in addition to the ambient light sensor on the side moving from the left side to the right with a slightly longer receiver". Oh, along with a new "space black" colour option.
The casing features a camera opening much larger than that of the iPhone 6, which Rock Fix claims is to support a new camera with a bigger CMOS sensor than the ones found in current models. This would still leave the iPhone 7's single camera behind a twin-lensed iPhone 7 Plus in terms of capabilities.
So, without a big departure from the iPhone 6 or 6s, the question for those owners may be how long before the iPhone 8 comes out for a meaningful upgrade, which is rumoured to have an all-glass chassis and edgeless screen.
