Remember, if you didn’t load the 2010 August 2012 Cumulative Update (CU) that the October one will also require SP1 to be installed.
Delays on the 2007 SharePoint and Project packages, and also the roll-up SharePoint/Project package for 2010. No 2007 client CU this cycle. So if you just need the individual Project Server 2010 October CU you are good to go! I’ll post again once I have an idea on the targeted release for the others – early indication is a couple of weeks…
*** Update 11/14/2012 - The individual 2010 Server package is out - still waiting for the roll-up, and an issue has been found with the 2007 Server package - see http://blogs.msdn.com/b/brismith/archive/2012/11/14/project-server-2007-issue-installing-the-october-2012-cumulative-update.aspx. ***
