DVD is increasingly showing a strain in providing HD content.

I'm not so sure in-game visual fidelity is really an issue. I hate to point this out because it's been said many times but, Crysis fit on 1 DVD. The issue here is that some of these games rely far too much on pre-rendered cutscenes, instead of simply making the cutscenes using the in-game assets. I like cutscenes as much as the next guy, but make smarter use of your resources, just because you have space doesn't mean you have to use it. Think if they had made all the cutscenes using less assets than CGI, this game could have been a 100+ hour playthrough without side quests!
