Hamburg word-of-mouth marketing conference disorganized?

So what the hell is going with that International word-of-mouth marketing conference, being held in Hamburg, previously announced here?
First, big names are crowning the list of invited speakers, so much so that the web page https://www.b-s-i.org/wom/en/ read like a who's who of viral and buzz marketing. There was Brian Clark, Lee and Dan, Dave Balter, Balder Olrik and so on were all listed as invited speakers. But one by one, they all dropped off the list for various reasons (Lee and Dan are far too busy working to just talk about it, for example.) Too many names on that list had been invited but not accepted, a bit like saying God will make an appearance - doesn't mean that he can make room in his schedule to do so.
Paul Marsden, Martin Oetting and Grey advertising were asked to come, had accepted but then were bumped off the speakers schedule due to some organisational mishap. Martin tells all about it on his own blog connected marketing, and it's almost a text book case in how to create bad word of mouth. The short email from the host of the conference, Nils Andres, simply states "we'll take your presentation from the [conference] program and are no longer interested in your coverage of it for Contagious magazine". Martin is bemused rather than upset, but other speakers who have been bumped off the program are far more annoyed (though they won't waste their breath speaking about it.)
So, if anyone here is still going/is there attending to that thing, let us know how it all turned out in the end will you? :) Curious minds want to know!
