After discussing it with a few members (as you saw), and failing to find a source for the GT interview, I've also decided to shelve the claim until further proof arises. But I just think that whole "SDF propaganda" talk is uncalled for, really. Regardless of intended platform, a multiplat move on an ambitious project like this could easily cause compromises, be it space issues, or engine restrictions, etc. Of course, that's all theories, and since we're aiming for practicality, like I said, I'll just drop it for now.

As for Resistance: Yes, but it also requires an install. Uncharted 2 has no install, but it has no loading times in the game...I can't help but question the duplicate files method.

Uncharted 2 has loads, they're just hidden by movies.

You don't experience loads when you die because when you hit a checkpoint it just saves the basic state of the game.  It can do that because there's not to re-setup when you load:

• Reset physics objects -- there aren't a lot of these so that's simple
• Despawn enemies - simple
• move Nathan - simple
• set weapon/ammo - simple

Reloading checkpoint done!  You don't really notice it because it doesn't actually reload the level there.

And I'm not downplaying anything there, I think that's a great design choice, I'm just saying Uncharted 2 does have loads but they're just hidden well.  If you want to know how long their insane load times are, just quit the game in the middle of a level and then come back to it.

Why would I regard that as criticism? Lol. But thanks, interesting read, short as it was.

I think R1 used duplicate files and R2 used duplicate and mandatory install (hence only about 100 and something MB). Madatory install is faster but of course takes up HDD space and is, well....mandatory (which can really suck in certain conditions).

And I said SDF type propaganda not blaming SDF themselves. But it's the sort of thing that fanboys start. In this case I'm fairly certain PS3 fanboys were behind this. I really do hope they don't hold back on the PS3 version and vice versa. So I expect uncompressed audio and video on PS3 and on one disc while I expect better AA (MSAA versus Quincux) and alpha effects on 360 (If you have both consoles you'll know what I mean by the alpha effects).

I could see how some people could see I was just putting down another PS3 because of the huge fanboy I apparently am.  :-p

Like I said many times, Uncharted 2 is a marvel so no worries in my saying anything about it.  While it's pretty common to mask load times with videos, I *really* like how they did checkpoints.

@ Twestern also.. (you really don't know this yet with all the threads there have been on it?)

Ok, let me try to explain this to you.. it's really quite simple. The bluray drive in the PS3 spins at a constant linear velocity (http://en.wikipedia.org/wiki/Constant_linear_velocity), this means it can always read at the same speed. The read speed of a 2X bluray is 9MBps (http://en.wikipedia.org/wiki/Blu-ray_Disc#Recording_speed).

Now, DVD drivers run with a constant angular velocity (http://en.wikipedia.org/wiki/Constant_angular_velocity), which means the read speed of the disc varies with how far the disc is being read relative to the center, or edge of the disc. Information at the edge is read fast, while info at the center is read slower.

Next, the drive in the 360 can run up to 12X DVD speed (http://en.wikipedia.org/wiki/Xbox_360_hardware#DVD_storage), BUT most, if not all games for the 360 are made on dual layer DVD-9's (http://en.wikipedia.org/wiki/Halo_3, http://en.wikipedia.org/wiki/Gears_of_war_2, http://en.wikipedia.org/wiki/Mass_effect, http://en.wikipedia.org/wiki/Forza_3, Just look at the summary thing on the right side of the page, it tells you the media format), which can only be read at a max speed of 8X.

The read speed of 8X dvd, as I said before, varies. It can go from a max of10.57MBps to a minimum of 4.36MBps, or 8X at the outer edge, to 3.3X at the inner edge. (http://forum.beyond3d.com/showthread.php?t=42157, somemore stuff there)

Ok, so to summarize, PS3 reads at 9, 360 reads at 4.36 to 10.57. Depending on where the information is on the disc, the bluray drive in the PS3 can outperform the DVD drive in the 360, and vice verca. So the 360 can read faster than the PS3, but NOT always, and NOT by that much, and so simply stating that the PS3 has a slow drive or that bluray reads slower than dvd is completely wrong.

Wait, but isn't FFXIII on a dual layer BluRay?

Does that mean the read for that will be slowed?

Well, I'll assume you have the internet, so why don't you find out for us.

I tried but couldn't find any info on it.  I found that writing dual layer takes twice as long, but didn't find anything on reading dual layer. 

Part of me makes me say well that obviously means that reading takes twice as long too! while another part says perhaps they don't list it because they're the same! and then another part tells me well they classify dual layer even if it's the same everywhere else! and then the voices start fighting and I don't know enough about this stuff to make a decision and my head hurts.

I want candy.

Bolded part doesn't make sense. Writing twice the amount will obviously take at least twice as long.

As far as reading is concerened, I haven't read anything about dual layer Blu Ray discs having a lower data transfer rate than single layer discs, so I assume they don't.
