When I inquired about this a few weeks ago, the Nature Publishing Group customer service representative informed me that: "Nature Communications" is only beginning to accept submissions for Open Access publishing on Oct. 20th, 2014. The actual OA publishing date is January 1, 2016."
Best to check-in with them, directly, though...
Hope this bit helps,
