If the rumours about the anniversary iPhone are true, they'd be releasing some pretty groundbreaking features whilst cutting the S-model tick-tock cycle by a year.
If this new iPhone is released and it does cost upwards of $1000, they'd likely be releasing it in tandem with the iPhone 7S, which will be at the standard pricing. If it's so groundbreaking with true wireless charging and no home button, it'll be paving the iPhone's form factor for the next decade. Then as component and technology costs go down, so will the phone.
If anything, this rumour of the high pricing has only made me excited, because it would indicate Apple are pulling products from their more-distant pipeline to once again revolutionise the smartphone market. If they've got a point to prove from a mind-blowing phone with features genuinely not seen on the market today, I can't see how it would cost less than $1000.
