yeah, i was wondering what was the point of that post too...

What was Konami complaining about then about not having enough space on a Blu-ray disk for MGS4?

it's all hype baby.

I don't see any significant amount of developers filling up 50 GB unless it's for lots of cutscenes and/or almost useless stuff like uncompressed audio. Filling it up with actual game content would mean spending far more money than current development budgets. Not even Sony's 1st party games have much more content than other games.

I don't think even in the next-gen we'll see many games using up 50 GB (unless it's for the stuff I mentioned before). The gaming industry is already spending too much on development as it stands...

I agree.  Filling a disk up to 50GB without duplication or lack of compression isn't making a game truly that size and I doubt any developers will have the budget to do 50GB worth of assets. 

No, single layer for Blu-ray is 25 gigs, dual is 50GB.  That is currently the max size.

Of course.  If you don't need to spend time trying to optimize disk space, why would you?  This was the same argument during the HD DVD vs Blu-ray days.  People would claim HD DVD's 30GB wasn't enough space because the disks were full.  Of course they were full!  Why wouldn't you always use the maximum the disk size would allow you?  Same thing applies, if they don't need to spend time with smart compression (due to disc SPACE, disc READ SPEED is a whole other consideration) then there is no reason to.

7.1 sound and japanese tracks helps =).

In the future, perhaps GT5. I'm sure FFXIII will do it.

It was reported my Media Molecule that LBP took up 40GB because of all the tutorial videos

Isn't there work on a 16 layered 400 gig one?
