The new design has your Google+ and Facebook profile links on the left with a few channels too. Trending and Popular links are placed right below that. Your subscriptions appear at the center of the home page which shows videos from the channels you have subscribed to. The recommended videos appear on the right. This is something I wanted The featured videos appear below the recommended ones.
To manage your subscriptions, when you click on “Manage”, the only thing that has changed is the navigation which has a black background. The like, dislike and Add To buttons would be heavier as you can see in the screenshot below. The flash player also has three icons which let you view the video in small player, large player and in full screen.
You would see the new design only if you are able to access YouTube as http://www.youtube.com/guide/ Here is a video by Sylvester Michael Johnson which shows you the new YouTube in Action.
