The name of the thread is stupid, this is a cutscene so we have no idea if it'll be the best looking game ever. The only in game screens that were released by GameInformer actually weren't very impressive to be honest.
That being said the trailer IS amazing and I'm loving the tone and atmosphere they are going for in this game. Its looking to be fantastic and who knows when we see some updated gameplay it very well may be the best looking ever, but it will have to come a long way from the little bit thats been shown.
