Well, the way I look at it, that image is old... Very old because the poll on "Diablo III's Graphics" only has like 50 votes. Nowadays that vote has 250+. But I wouldn't doubt if Blizzard would help make the site a little cooler looking to attract more members before turning the site into a Diablo III game homepage.
Yes, I did notice that, and I also thought it was kinda cool that Diablo on the left side is kinda looking at him.
