A full hour of the game play for Watch_Dogs before putting in markets by four days

Today when I watch YouTube, i found a video clip of GameSpot Channel.
Shows a full hour of game play of Watch_Dogs before put in markets at May 27, 2014
And the game on a PS4. And shows game play graphics and dynamic own movement and has not been played any mission section
So as not to spoil the game on the players.
