Indeed. But GoW doesn't have CGI (except for some parts, but all arte short). MGS 4 doesn't have it too and I'm pretty sure that Uncharted doesn't have too (or at least have only a few). All that GBs are pure game size...

The point I was making was that Nintendo are clearly interested in that technology in general. InPhase wasn't the only company working on Holographic discs, just the one that holds the joint-patent with Nintendo. Also, the company hasn't actually gone down, it's declared bankruptcy - there is actually a difference. The company does still exist.

EDIT: Hmmm... looks like they've sold off most of their assets, though. Interestingly, someone picked them up, and are preparing to start shipping very soon:

Anyway, looks like they may actually have found a way around the flaws that InPhase had, and have a better business plan. I don't have a clue what the prices are going to look like, though.

"a few years ago" is a fairly long time. Also, the discs only cost $180. It was the reader that cost thousands of dollars.

It takes lots of R&D and expensive early products to develop new technology. Of course they were going to be expensive.

And yes, I was talking about what comes after Wii U - the next generation after the upcoming one. And while we can speculate about whether the market will still be there (I expect that it will, although it may look somewhat different), it's just as interesting to speculate on where Nintendo is expecting to go, and I think they have their eye on holographic media.

Anyway, I'm not suggesting that Nintendo would be "introducing" the new media. I'm suggesting that they intend to hold a few key patents, and then use it in their future consoles - thereby forcing competitors to either pay royalties or find an alternative medium. Can you think of another reason why Nintendo would have partnered with InPhase to such an extent that they now hold a joint patent?

GoW 3 has a 2.5h HD making of doco on the disc 

as for Uncharted 3 

"There are some "luxuries" in that allocation - 3.24GB of behind-the-scenes movies, 7GB of foreign language audio, and 10GB of 3D movies (pre-rendered cut-scenes are stored both in 2D and 3D versions) but by our reckoning there's at least 16GB of core game data being used in this game"

from digital foundry

Also the Blu-Ray drive has long seek times which means devs use a lot of data duplication to minimise load times as well, the technique is used on 360 as well but less so as disc space is at a premium on that side and seek times are slightly better. 

I've read data that states they can hold as much as 500GB in test environments...

This is why I don't see Digital Games as massive of a proffit as some developers and gamers think. I have to wait 3-5 days to download 7gb games (daring only to leave my PS3 on for eight hours)...50gb or even 10bg I would not even bother downloading.

So, the guy in charge of tech and making this engine should worrying about things that aren't his job?

Going digital makes more sense in PCs as the game can be heavily compressed as we have to install the game before playing it, unlike consoles.

That's why games that take 2 DVDs on the Xbox360 come only in 1 disc on PC.

His bosses should be sending him in a less wasteful direction. I'm sure he's doing good at what he's been told to do, but shouldn't have been told to do it.

Some developers have not benefited from the additional space optical discs have provided. Square Enix is one of them. I mean FFXIII was only 6.8GB without the CG. It has 31.6GB of CG. They need to get their priorities straight. They need to get back to making RPGS with great characters, stories, with expansive worlds.
