We know that at least 323 received a broken PS4. At least 492 received a working PS4.

I would guess that 1/10 would write a review when the PS4 is broken and 1/1000 would write a review regardless.

Also we don't know if these are real reviews or just 323 Microsoft employees who were given money to order the PS4 and then post a bad review :P
