As far as I know... yes... when you have Premiere Pro CC you are allowed to install the special Cloud version of Premiere Pro CS6... when you activate PProCS6, the bundled EncoreCS6 activates
The bottom of page #5 at The PPro/Encore tutorial list http://forums.adobe.com/message/2276578 has more information
I believe that John is correct. But I do not have CC, and have not tested this. Is there anyone out there that has the Premiere CC ONLY that can confirm this?
