Those animations are to be similar to the fluid visuals already on the Apple Watch, Gurman says.
If that's true, there's a chance Apple changes its iPhone display technology from LCD to the more power efficient OLED used on its watch. Even if that doesn't happen with the 2015 iPhone models, I anticipate Apple will eventually make the move once it's happy with the display output.
Surely, the iPhone 6s and anticipated 6s Plus will have a next-generation Apple processor inside as well.
I still think at least one, if not both, of the new models will have 2 GB of memory to assist with the split-screen and multitasking features Apple is introducing in iOS 9.
In terms of the camera hardware, Gurman says we'll see a jump from the current 8 megapixel sensor in the iPhone 6 line: a 12 megapixel sensor will be in the 6s phones. The front-facing camera is expected to get an upgrade -- I'm guessing a 2 megapixel sensor -- as well as its own flash.
Along with the higher resolution still image possibilities, 4K video recording will reportedly also be supported.
That makes sense: Even if few have 4K television sets, some competing Android handsets gained 4K video support last year.
