this is more likely a reportage of what you sense around these parts of the internet.I also think the hype for the iPhone X will die out quickly, meaning those who wants to get it already know they will get it, they've been waiting for it, creating a high demand at first, but will quickly lower.
iPhone X is not the type of walk-in and buy type of phone because of its cost and a few things users might find it deal-breaker
but as far as the general population is concerned... i'd be willing to bet far more iPhone X will be sold after the initial wave/hype..
an example using numbers from thin air-- 30 million sold in first two months... 100million sold in total.
