This is strange. Somebody posted this on the iOS 9 wishlist thread

It shows that iOS 9 and iOS 8.4 are in testing. But that's not what intrigued me. There is a new phone, iPhone8,1, which is said to be 667x375. At first I thought it was 4.7 inches, because it is half (or quarter) the iPhone 6 resolution (1334x750), which makes sense as the iPhone 6 has twice the pixel density of the original iPhone. But then I checked the size of iPhone7,1 (the iPhone 6 plus) according to this scale, and it says that it is 5.2 inches, even though we know for a fact that it is 5.5. So I checked the size of iPhone8,1 according to that scale, and it says it is 5 inches.
I'm not an analyst, and I don't have any other data to prove it, but I am curious; will we see a 5-inch iPhone this year?
