Bethesda won't announce TES VI until they're finished with Fallout 4. If they follow their DLC release schedules they had for Morrowind, Oblivion, Fallout 3, and Skyrim, the final DLC for Fallout 4 will come out around October or November 2016.

For reference, Morrowind came out May 2002  its final DLC came out June 2003,  Oblivion March 2006 - March 2007, Fallout 3 October 2008 -  August 2009, and  Skyrim November 2011 -  December 2012.

I'd expect TES VI to be announced at E3 2017 and released November or December 2017.
