DLC has redered Blue ray disc to be pointless. Apples newest laptops dont even have a DVD Player!!! Nothing!

Well Explain LBP then?   I have heard it takes up 40GB of space on a Dual Layer 50GB Blu-ray Disc.  How would that fit on a DVD?  Would the Story mode levels have to be DLC then? 

 

 

 Sony also said that Heavenly Sword has 9 gigs of music. Sony is just trying to justify their media format. If games like Fable 2, GTA 4, Gears of wAr 2, Mass Effect, can all fit on a DVD, it should be able to burp LPB. Resistence Fall of man was also supposed to be like 17 gigs according to Sony.
