Good thing I'm playing on PS3.
Blue-ray is just more space..it also uses a different colour lazer that reads a little faster,( hence blu-ray ) but not much. There is no need for PS3 to be blue-ray.
Blu-ray is what essentially held sony back in the console race,it was too expensive,thus is why PS3's cost so much when released.Alot of games on PS3 require you to install to the hard-drive...thus whats the point of blue-ray on PS3?...besides movies...and even then the difference isn't that great.
Forza had two disks,but you only used one ever,because the other was installed on the hard-drive. If blue-ray is so good ,then why have alot of games on PS3 install to hard-drive?
Putting games on the hard-drive,de-creases load times. It doesn't matter if a game is 1,2 or 3 disc's,it goes on the hard-drive anyway,which means you only ever need the one disc.
Also take into account that new tech and new techniques are always improving....meaning they know how to cram more info on one disc,without losing quality.
Also installing on the hard-drive also increases the chance of longer console life,it keeps the systems cooler,the lens etc is not needed to constantly read stuff. That has now been digitally and magnetically been stored on the hard-drive....Why do alot of PS3 games require you to install to hard-drive,if you have blue-ray?...to me it makes it more or less useless on the PS3 console.
PS3 users ( some ) say xbox not having blue-ray,will lead to it's downfall or make it weaker etc,nothing could be further from the truth.
Thing is,there is no need for some of of this stuff/ or gadgets etc,it's just a money making ploy. It happens everywhere.
Thats my opinion.
