It took me two attempts with PS Direct. I used every old phone, computer, and tablet in the house. I think I had 8 or 9 devices waiting to be put into the Queue via direct. The first day everything was sold out by the time my first device got through. The second day, the disc version was sold out but I was plenty happy with the digital version and I snagged it up. Interestingly it looked like a second device was going to get in too, it only had a couple of minutes left but I shut everything down so people go move along in the queue.
On a side note, I was pleasantly surprised to find they give free shipping if you have PS+
