It’s easy enough to prepare a USB drive to patch the machine, simply involving the creation of a few specific directories so the PS4 knows where to look. (PlayStation 3 worked this way, too.)
The step-by-step directions are, again, available right here.
(By the way, I really love that the updates are called PUP files.)
Of course, if you're not picking up a PS4, make sure to tune into our day-long livestream on Friday, which I'll also be in town for!
