YouTube experimenting with new user interface

After many small tweaks youtube is onto something really big. A video posted by an Google+ user on YouTube shows the new interface

The thumbnails are a lot bigger and now take up to whole width of screen. Also each video is playable on the list page without opening a separate page for individual video. There are also some minor tweaks in the buttons etc. Check out the video below.

This would be a major change to the interface which may take some time to rollout. Do you like the new interface? Leave your comments below
