Is YouTube testing a new interface?

So when I opened up YouTube this morning this is what I came across:

I actually think it's a nice clean interface. Especially for videos:

So what do you guys think? Have you got it yet?

P.S. Sorry about posting in the Android Army about this I'm a strong advocate for a separate Google Forum!
