Agreed, the leaked videos are certainly not some kind of viral Sony advertising.
Civilians have their hands on the game, deal with it.
The low quality videos are simply the result of people having low quality video recorders... not some super huge secret conspiracy by Sony to advertise the game in a low quality manner which continues to hide the precious (high res) details we all want. That train of thought is foolish, so lets drop it.
Sony's advertisements will be high resolution and in your face. Kevin Butler will be cracking jokes, there will be guitar rifts, and confetti... you will know when Sony starts advertising.
your one of them!
