They're too busy with Saint Seiya & other stuff to start working on more Crystal right now. If any announcement happens, it'll probably be sometime after they're done with Tiger Mask W (which at 39 episodes will end airing in Summer '17) or Appmon (which assuming it's a year long like most Digimon shows, will probably end in Fall '17).
I'm feeling pretty much the same way myself. The only positive bit of hope I can offer is considering Dragon Ball Super is going into its Universal Survival Arc (how can you top that?!) in February, I think it is going to conclude next year after another 30 more episodes or so.
Although it is frustrating to continue to see Sailor Moon get shafted and not made a priority by Toei, all of this may be for the best. The last two arcs of Sailor Moon have the most changes and exciting things for fans to see. If waiting longer means we get Chiaki Kon back and some decent effort put into the rest of the series, I can by all means wait till early 2018. I for one can tide myself over with all the Viz releases, which I haven't even bought or watched at all. As long as they do a combo 22-24 episodes altogether every week wrapping up the entire series altogether.
All of this makes me wonder how much new merchandise we will see next year and if we will see a Stars musical in the fall despite Toei being a season behind. I know we are getting two more Figuarts Zeros, the Kaleidemoonscope, and the Tuxedo Mirage memorial ornament, but that's about it.
