When the rumor first came to light, they all said that this 5se would look like a 5S with 6 or 6S internals, or something like that. Lately, I've been reading that it will look more like the newer generations of iPhone and may even have a protruding camera as well. At the very least, a strong rumor is that the glass will be curved, even if in a 5S-like casing....in turn, highly unlikely old cases would work with the rumored device, if we even see the device. It is just rumor at this point afterall.
