I was listening to this week’s Rebel FM podcast and Arthur Gies said that he had played through Assassins Creed Black IV Black Flag on the PS4. He also stated that it took him 36 hours playing Friday through Sunday. I highly doubt that it was a review event. Later in the podcast, he indicated that he picked up the PS4 controller, during the podcast, and was looking at the back and comparing the audio jack it to the Xbox 360's audio input.
So what do you think, do gaming reviews have the new system already? We're only 27 days out (in the US) and it doesn't seem like it is outside of the realm of possibility
