Disappearing date!

[Brent]

What's happened to the Vienna Stadthalle date, that was scheduled for 29 November 2011? It was listed on this site's tour date section, but no more, & has also gone from the venue's website.
I live in Nottingham, UK & was planning to travel over for what would have been the final date of the tour...

In fact, while I'm on the subject, why aren't they winding the tour up in Germany? I would have thought Hannover would be the natural place to symbolically 'end' it all...
