Well, I was just responding to the people above who said this game would be one 1-2 BD 

I guess my sarcasm detector is broken  

^ very broken my friend hehe

Has any ps3 game used full blu ray disk space?

That game was totally uncompressed IIRC, plus it included MGO on the same disc.

EDIT: Also, that could have been an exagerration by Kojima, pre-release, that was used to try and garner awe/attention for his product.

I believe they will use a different video file than the ps3 for the cut-scenes, Microsoft has a couple out there like VC1 and WMVHD, which both compresses video, but still have good quality results, this will reduce the amount of data needed to fit on the disks.

The in-game assets will remain the same, and like I posted many times, I see 4 Dual-layerd DVDs max, that's about 30 gigs, plenty of space in my opinion, even for a final fantasy game.

.......point?

It still ansewered the question about a ps3 game that actually used the full bluray space.

The 360 will use a few disks. Meh I'll live

 I don't think the 360 will need to compress sound files.

OK, even so, that doesn't mean that there will ever be a game which uses more than one BD, which was my primary point.

It's 5.09GB, not 5.9GB.
