If it is to come to fruition it sounds to me like that an annoncement 2015 for 2016 release, but as they say they have not decided yet as to whether they will release it or not, but now possibility.
Take K mount seriously is good as legacy lenses will work, perhaps SR for FF will be in lens instead of in body.
