People here only think about the advantages of Blu-ray. Of course PS3 is a better console with blu-ray. However, blu-ray helped Ps3 sales? I know that BD was a reason for many sales of the console, but I am certain that would be better if PS3 launched for $100-$200 less without Blu-ray. Actually, the game world would be a lot different than now. PS3 could even win console wars.
