Comment on December 2015 CU for SharePoint 2010 is available for download by Stefan Goßner

Hi Demetris,
security fixes for SharePoint 2010 will be provided till end of extended support – so roughly another 5 years.
Regarding non-security fixes: there is still a backlog of hotfix requests which were requested and accepted before end of mainstream support. Till this backlog is processes there will be CUs but the number of non-security fixes in these CUs will get smaller and smaller from month to month.
Cheers,
Stefan
