New Passport Launch?

I went to sign into MyMSN tonight, and I was greeted with a completely different Passport sign-in page. Clicking through for more details brings me to a different Passport home page than I've seen before. When I signed in, I was asked a bunch of information about my birthdate, etc... and then I had to agree to a new terms of service.

Anyone have any details on what's new with Passport?
