Yup, they'll be showing more features in future shows, including the features that are added via the patches, like the mechanical damage and online leaderboards (coming late december).
For a game with so much content (they even admitted it tops the grand majority of PC sims in content as well), it's normal to have such a massive review.
I pity those "reviewers" who think that a couple of hours with GT5 is enough to give an actual review of it.
