Microsoft released their Security Bulletin Advance Notification on Thursday afternoon.  Next Tuesday appears to be a very active day as there are 12 security bulletins that will be released as well as 2 High Priority (though not security based) updates.  In addition, the Malicious Software Removal Tool will have its monthly update.

From http://www.microsoft.com/technet/security/bulletin/advance.mspx:

* Ten Microsoft Security Bulletins affecting Microsoft Windows. The highest Maximum Severity rating for these is Critical. These updates will be detectable using the Microsoft Baseline Security Analyzer and the Enterprise Scan Tool. Some of these updates will require a restart.

* Two Microsoft Security Bulletins affecting Microsoft Office. The highest Maximum Severity rating for these is Critical. These updates will be detectable using the Microsoft Baseline Security Analyzer. These updates may require a restart.
