Just wait for reports from Sony. I can understand that people don't wanna wait, but waiting for numbers that are always wrong isn't really worth squat.
Basically someones said it did X amount to which it then gets dozens of replies worth over then later its revelaed to be Y amount all long.
Its like with the preorders, last week they said Black Ops 2 had 1.2 million preorders on Xbox, now that number has changed to 1.5 million, they were off by 300k?
