I Do Not Think Game Worlds Will Increase in Size This Gen :(

If Skyrim can fit on a 9GB disc(xbox dvd?), I'm sure with 50GB (double layer Blu-ray) we will see vast improvements in terms of scale, density and graphical fidelity. I think most space is taken up by video and audio anyways...

I personally think worlds don't need to be much bigger, just more responsive.
