Google Video's popular section now leads to a top 100 page showing the videos gaining in popularity and those losing popularity. It also shows the videos that are new to the popular list.

Do you have a screenshot and URL
'Cause I'm just getting the normal search results, 15 a time in grid view
http://video.google.com/videopopularpage?num=15

It is here:

http://video.google.com/videoranking

There is a link from the homepage.

Although the current number one video is absolutely rubbish in my opinion. Number 2 (juggling) is much better.
