vcap6-dtm deploy has quite a bit of mirage, app volumes, a bit of IDM & vrops and some more Horizon. There are several study guide for it, just google vcap6-dtm deploy study guide.
As fas as the vcap7-dtm deploy: the dcv & cma deploys got priority since those are taken more often and they haven't been released yet either. Don't expect anything for the dtm deploy before the end of the year or even within the next 6 months.
