The Nissin Di700A has just been released in Germany (sold via third party at Amazon.de). Thanks to the FR-reader, who dropped me this link to 43rumors.
We reported about the (radio controlled) Nissin Di700A flash for Fujifilm X back in March 2016 here. At that time, the flash was scheduled to be available for Fuji X within Summer.
