I'm 100% certain it will sell out at the release and you will have to wait few months to get it. I don't know where people get the idea that only few people will be able to afford that phone.

The idea that most people can’t afford a $2,000 phone?

The idea that few people can.

A bit fallacious because if you've been supporting the proper size classes API and not hardcoding assumptions about windows/orientation/etc. (as Apple has been telling you to do every WWDC for like 10 years now), there's basically 0 work to do.
