Yes, it will work the same. You can choose Facebook or Google when you register, or do neither and sign up with your email address the old-fashioned way, and you can link your existing account with Google just like you always could with Facebook in the right-most tab in your preferences. There, you can also disconnect it again.

Your Google account is usually your Google email address, which you can use on all sorts of other Google products. It's not specifically a Google+ account.

We'll update the corresponding help pages once this is released, too.
