While we will see improvments in graphics as the gen goes on, we won't see as big of a jump as last gen. Last gen was the first HD gen, which meant that devs had to figure out how to optimize their games for the new standard. Just take a look at how much Nintendo is struggling with adapting to HD. This time around, the devs know what they're doing.

Furthermore, I think VGChartz should add a "Like"-button.
