This is so true.
The majority of people will not pay that much for an iPhone, and if all the investors and banks are going all in on Apple and thinking that they will make the most money off of this next iPhone, there's no way they can make it so expensive that only very few will buy it. That doesn't add up to what the rest of the world and Wall Street think about the iPhone 8. Sure there will be the 7s and 7s Plus (reportedly) to make some money for them, but the bulk is supposed to be made from the one that everyone is looking at, the iPhone 8. If it is priced too high for ridiculous reasons as they can't make a lot during launch, then it will not do nearly as well as everyone is thinking. Also, I sold Samsung and Apple devices, and I noticed that it is almost always true that carriers offer more discounts for Samsung devices than Apple devices. If there is a $200 gift card for Samsung's latest, then there is a $150 or $100 gift card (if any) for the iPhone. That means that there will be way more deals for Samsung devices than Apple devices, and there aren't enough die-hard fans to purchase enough iPhone 8 models to offset the majority of people buying a Samsung because it is so much cheaper. So they could really suffer if they build an iPhone that costs too much.
Then again, the prices are all rumors, and Apple and Samsung are smart, so I think the next phones, the upcoming Note and iPhone, will be priced better than what people are guessing.
