Carmack: Doom 4 Is So Big It May Not Fit On PS3 Bluray Discs

[SvennoJ]

Do they mean single layer or double layer blu-ray.
If it doesn't fit on a 54gb blu-ray disc then I'm out anyway for a steam version with my 40gb cap.

There's no way they fill that much data with textures, maybe they have loads of 1080p pre-rendered video.
50gb is over 12 thousand 3888x2592 pictures. I don't see that much variety in a doom game...
