If you notice since the iPhone 5s Apple has been releasing what I call a unicorn iPhone " the iPhone that is near impossible to find" to create a media and consumer frenzy.I honestly believe this could happen, a special dual lens model above the regular 7 Plus.
The thing is, if they can produce enough, the Plus should have the dual lens standard. That is the point of an iPhone, it's suppose to be the very best from Apple.
However, I can almost understand if the yield for the dual lens can't produce enough, but I'm telling you, most people are going to want the dual lens even if it's another $100 on top of the regular 7 Plus so the waits on the device would be massive.
I just think it's a shame though as we all know during some of Apple's worst years, they started this fragmentation and small differences between models.
The simplicity of before was nice, but perhaps the business isn't sustainable that way. I don't know.
