No Microsoft changed it up a bit. They removed a few editions with the release of 2012.
Data Center edition is unchanged
Enterprise edition in 2008 is now Standard
Web edition of 2008 gone. No direct replacement.
HPC edition of 2008 gone, replaced with Standard. There is an HPC Pack for 2012.
Small Business Server 2011 Essentials is replaced with 2012 Essentials
Small Business Server 2011 Standard has no direct replacement. Use Standard 2012
SBS Premium is now basically Server 2012 Standard with SQL Server added.
So basically there are far fewer editions, and many old ones are now served by Server 2012 Standard Edition.
