I'd be willing to bet the venn diagram of people who line up for phone launches and people who drop $$$ on consoles does not have a very large overlap.
And those things don't have anything to do with each other anyways. Factoring in taxes this thing's launch cost is like $250 more than the PS4. Even the $500+tax is an absurd amount of money to drop on something that has no ability to play physical media.
I honestly can't see the PS5 selling anywhere near as many units as the PS4.
