People can complain about the downgrade based on poorly compressed or off screen footage all they want, but a lot of the impressions I'm hearing from people actually at TGS is that the game looks gorgeous. On the CAGcast tonight they were saying it's the only thing at TGS that actually looks "next gen".
My only concern is GG overdo it and forget about the gameplay and art. Don't want the game to be too clean and "technical".
