Since I'm not using 2012, yet, I didn't know about SEQUENCE. So, I looked it up and found a nice Technet article by Denny Cherry.
He not only explains what it is but also why you might use it.

Yeah, I noticed there weren't really use cases on MSDN or the cited article. It wouldn't have been introduced if it wasn't useful, but I'm having trouble coming up with a case where I would use it. Then again, we've only had 2012 here for about a week and a half. Thanks for the article with use cases!

Maybe it's included because people coming from Oracle asked for it.

Oh yeah? I'm really not familiar with Oracle. What kind of real-world stuff would you use this for? Either in SQL or Oracle.

As far as I know, because I'm not that familiar with oracle either, Oracle doesn't have an Identity functionality as SQL Server has. That's why they use sequence.

Looking for information to confirm this, I found that they included something similar in Oracle until 12c, so before that, sequence was the way to go.

Oh, okay, that makes a lot of sense then. Thank you! It's more the 'across multiple tables or outside of tables' thing I'm having trouble finding use cases for.
