It seems YouTube are testing (possibly launched) a new way of showing related videos at the end of a video. From what used to be only a few choices with big buttons to share, replay etc has now turned into 12 thumbnails with titles overlaid and simple share, replay and vote buttons at the top.

 

I quite like it, and it should keep more people on YouTube (not that thats hard) and hopefully it will also increase related video views.

So everyone wins!
