I frequently see the question asking if/when will Service Pack 2 for SharePoint 2010 will be released. I don't know when, but if we look at the following KB article, it appears there will be a Service Pack 2 for SP2010. It will add support for Windows Server 2012. As always, things can change. I'm reading the same KB article that you are. My crystal ball is in the shop this week.
SharePoint 2010 SP2 is out!
however, supported operating system only lists Windows Server 2008. Either they forgot to list Windows Server 2012 or it still does not support it.
It's available, but apparently doesn't support Windows 2012 yet. Read more here: imperfectit.blogspot.ca/.../sharepoint-2010-service-pack-2-now.html
