"Try to wrap your head around that for a second. Read that headline just a few more times to make sure that you aren’t confusing it with one of the ads on the side of the page of something. Got it? Good, because Kojima-san is not playing around when it comes to the file size of MGS4. In an interview with a Japanese mag, the Metal Gear Solid creator claimed that a 50GB Blu-ray is not sufficient for his upcoming title. Apparently, the team had to compress certain parts of the game to get it to fit on the Sony format, and foreign voice tracks were cut completely.

Kojima : I am not satisfied with the quality yet, however…there isn’t enough space.
Interviewer: Not enough space on Blu-ray?
Kojima: Yes. [laughter] Not enough space.

Someone get this man a Quad-Layer BD!"

wow crazy...how did he pull that off?

Holy......... 50GB game........ *mouth begins to water*

It would take 50 Wiis to hold that game!

*Seriously, how big are games going to get? That's f***ing huge man!!!

If that does not fit, then why not use the 100GB Blu-ray disc?

what's the limitation of using 50gb two layers Blu-Ray disc? Firmware upgrade? or Hardware upgrade?

He wants higher quality by not compressing the crap out of everything like they do on dvd.

I expect most of the data to be doubled up like we've seen other PS3 games utilize to lower disc access times. I seriously doubt they've maxed the disc. It's a marketing ploy.

I agree, no load times(not much anyway) and less than 10MB of install on the HDD.

can't wait for xbox 360 version
