It starts to make sense now. Apple will retire the "plus" version and replace it with the "pro" instead to make it consistent with other product lines (ipad and Macbook) There will be 2 versions: iphone 7 and iphone 7 pro. However, unlike the "plus", the iPhone "pro" won't be $100 more than the smaller one. It's probably $150 more since it has far more features (dual camera, 3gb ram, 1080p screen) . Just like what they did with the iPad.
Yep just Apple doing Apple things.. Them greedy bastards...
