John Stocker, voice director for the Sailor Moon S and SuperS series of Sailor Moon as well as the movies, mentioned at Anime North 2013 that FUNimation has the rights to dub the new Sailor Moon anime.
This is not an official announcement but it since John Stocker works in the voice acting industry he may have access to this sort of information. However, it was mentioned that this has been in the works for three years now, which could be refreing to what was or currently is a redubbing of the original Sailor Moon anime rather than the new show. Whoever holds the rights to dub the original anime may very well also have the rights to dub the new Sailor Moon anime which we are currently expecting to begin airing later this year or early in 2014, regardless
