Microsoft has just released Service Pack 2 for SharePoint 2010. It is available for download here: http://support.microsoft.com/kb/2687453.
Service Pack 2 adds support for Windows Server 2012. It is important to note, however, that due to changes in the Prerequisites Installer, you will have to obtain the SharePoint 2010 with Service Pack 2 media rather than slipstreaming the update. As of now, it is not yet available on MSDN for download.
