I'm not so sure they will sell a ton. Most of the talk I've heard has been "meh" regarding it. I'm personally holding off until I see more hands on reviews and feel comfortable that I wont be a beta tester for Apple.

I'm really excited for the screen (not the notch). True blacks are where Apple has really suffered. I love reading at night on my iPad but it's a much worse experience than my Samsung tablet with an OLED screen. The move to OLED by Apple is really the biggest thing here that people aren't paying much attention too.
