The Sailor Moon Crystal anime is scheduled to begin streaming worldwide on NicoNico next month, and as reported earlier, Viz Media have licensed the series for distribution in North America.
Today Viz shared an English-subtitled trailer for the anime via their YouTube channel, which you can watch above. The trailer appears to be the same one that was streamed earlier in the month.
Sailor Moon Crystal will begin streaming on NicoNico on July 5th at 7 pm JST. It will stream on the first and third Saturday of every month.
