The London drupal community has thrown a bid into the hat to host DrupalCon 2011. It is a strong bid from a strong team for one of the best cities in the world. So just vote in the poll The preferred venue is Southbank Centre. It tickles me silly to just compare that to a leg of lamb. Don't ask. Ok. Fine. won't be that cruel. Just imagine a pub and food - that's one memory from the first Drupal meet in London. And now Southbank...
There are community polls out on g.d.o for DrupalCon2010 and DrupalCon2011 in Europe. These polls do matter, but are not deal breakers. They are there to reflect the community preference.
And just one last note - I would love Berlin for 2010. I love that city, especially East Berlin. Sorry Copenhagen =(
