During a conference call with reporters to tout Fox’s 2016-17 schedule, chairman and CEO Dana Walden confirmed that
there have been “conversations” with series creator Chris Carter and
stars David Duchovny and Gillian Anderson, adding, “I believe everyone
is on board to do another installment of the show.” Walden conceded that
there will be some scheduling hurdles to overcome, but, “Hopefully,
this time next year we will have more news.”
Based on this news, it's obvious that we won't get Season 11 until the 2017-18 TV season at the earliest.
