I was told by 2 different people at PS Support that it was suppose to come out today(1/6/14). So today I go on my PS4 to see if there is a update and nothing at all and then I go look online today via Google and saw not one thing about the update online.
Firmware 1.53 will come out...Spoilerbefore firmware 1.54. I'm sure of it.
Edit: As the OP's question has been sufficiently answered, this thread will now be locked.
