iPhone 7. Just because.

Securities analyst Ming-Chi Kuo, who has a respectable track record at reporting on Apple's upcoming plans, issued a note to investors on Thursday that claims the next-generation iPhone will have a FPC-made capacitive Force Touch sensor under the backlight, laminated with metal shielding. Kuo adds that the change may be significant enough for Apple to call its next iPhone the “iPhone 7” instead of the so-called “iPhone 6s.”
