I always argues on forums how much annoying it is with all the hardware talk & crap. But I never really saw something different between each game on a similar system.
I think he's meaning that arguing the theoretical pro\cons of current hardware is meaningless when the actual games produced look and play almost identically.
Well, yes! Better hardware can produce better games when the art isn't holding you back. What possible reason is there to doubt that when we can see for ourselves in improvements in technology and what they net us.
