I am mainly curious to see whether sales drop dramatically when Apple removes the 3.5mm jack or not.
This is neither a "diss Apple" nor "if you can't afford $199 headphones don't buy an iPhone" post.
I kinda like to diss Apple now days so I hope that the iP7 sales hurt if there's no 3.5mm headphone jack...But as Marques Brownlee states in his new video: Apple has a habit to drop this and that; people get angry at first but in the end they all get used to the new "Apple norm". So, no: iPhone 7 sales are gonna break records once again...
