[quote name='dmaul1114']Keep in mind here that you're arguing that one of the longest games ever made, with one of the biggest game worlds ever created, PLUS two expansions for it could almost fit on one DVD probably.
DVDs are enough space for most games this generation, and most games can be put on multiple discs. It's really just an issue with these types of open ended games were you have one big world/city your zig zagging across as it would be annoying to have say half the world on one disc and half on the other.

Throw in some uncompressed cutscenes, a few lengthy bits of dialogue, perhaps some big textures that don't repeat and make the world seem like a 1960's cartoon, and a large worldmap (regardless of game length), and I think we can see multiple DVDs. Whether that is a good thing or not is left up to the historians who look back on this generation's game consoles....
There were similar issues when CD-Roms first came on the scene for PC games... lots of shovelware (filler) came out early on, because game studios wanted to fill them up, but didn't have the ideas or design concepts in place to make larger, more immersive games... so they added FMV, some uncompressed audio tracks and voila! CD-sized game!

Later, games became mindful of the content, and made decent games on the media (sometimes on multiple discs like Planescape:Tormet... an EXCELLENT RPG)..
In the case of Blu-Ray, however... it's not necessarily Sony's proactive response to the inevitable size constraints (which I think given their console lifecycles, might actually have been a consideration), but the format war w/r/t DVD's successor that is the sticking point with the PS3 (and those who find it vastly overpriced at the moment.)
I think Sony could've hit the $400 pricepoint, came out with a $300 add-on for Blu-Ray like the HD-DVD add-on for the 360, and we'd be having a very different conversation... (albeit, probably a negative one about the PS3, given the development hurdles and all). But that's parallel universe talk... and in _this_ universe, we focus on the now.
I am not as vocal a critic about the PS3 w/r/t price, because I feel like it will (and has already) delivered a worthy experience for what I paid for it. (I bought a 20GB, and threw in a 120GB hdd). Still, I am not going to say that the price is for everyone, and those who balk at the higher price have rocks in their skulls. To each his own, YMMV, and results are not typical.

For me, I didn't think the 360 was overpriced (albeit a bit shoddy... though I bought an elite recently to remedy that.)
I wonder how 2008 will pan out with lots of cross-platform gaming coming in the bigger titles from the larger (not-EA) studios.... heck, even the fellow who recently took the helm of EA stated that the PS3 was going to be more on par with the 360 under his watch... thus possibly nullifying the "we're focusing on the 360" comments of the previous guard...
