Interesting...and even Hideo Kojima himself (Metal Gear Solid creator) who said that even a dual layer 50GB blu-ray disc wasnt enough to hold information in Metal Gear Solid 4.
Of course, I think it is because of dolby digital surround sound, and those weird ass "Japanese commericals" that put up too much information into the disc.
Oh well...the cutscenes are obviously alot longer than Metal Gear Solid 2 and Metal Gear solid 3's cutscenes so yea it still beat it.
Now I wonder if Hideo Kojima is considering of using that disc for the next Metal Gear Solid game? Now that would be very interesting to see how it works...
however, with those kind of discs, I bet they would be even more expensive than the blu-ray discs. :/
Let's see what the future lies ahead of us.
