No doubt people will start posting compare screens around here once they get their discs, but make sure you read moth3rs excellent post about what to look for when comparing screenshots - at first glance one image might look better than another, but then you realise that the 'better' one might just be more contrastly and lacking detail in the shadow areas and light areas and so on.

Of course, it looks different on your TV to on the computer as well, and individuals vary in their preferences.

Still, comparing is fun, and stuff pointed out in compares tends to help raise the bar in general.
