>if I understand this correctly, there will be no Wikimania 2017. 
My understanding, having been part of the recent discussion on Meta about the future of Wikimania, is that Wikimania 2017 will take place in Montreal as scheduled. Beyond that, the question is whether the next Wikimania will be in 2018 or ‘19, since one of the options under consideration is making it a biennial event rather than an annual one.
