This was just published on the site of the Nederlandse Bridge Bond (NBB, the Dutch NCBO):
The WBF, Mr. Melchers (sponsor) and the NBB have been investigating since last summer if the NBB could organize the 2019 Bermuda Bowl in the Netherlands. Parties did sign a letter of intent in June 2016, which ran until November 30th. Unfortunately, the conclusion had to be drawn that the negotiations between the parties have not led to a positive result. The NBB has notified the WBF that the NBB cannot organize the 2019 Bermuda Bowl.
