John Mueller from the Google Webmaster team posted in the Google Webmaster Help forums they are having a new Google Webmaster Central Hangout tomorrow, Friday the 26th, at 5AM EDT (clearly meant for people in the European countries).
The time is 11am Zurich time, so if you are in New York that is at 5am on Friday, if you are elsewhere see this time chart for the conversions. Don't worry, Google has these hangouts often and they vary the times to cover US webmasters, European and Asian.
I’ve added a few topic suggestions below (http://goo.gl/HTMgW) - go ahead and +1 the entries that you’d like to focus on, or add your own as replies. If there’s sufficient demand, I can prepare something short so that we have lots of time for your questions. If we have time, feel free to bring your web-search-related questions as well!
You can find out more about Hangouts at http://www.google.com/support/plus/bin/topic.py?hl=en&topic=1257349 - having a webcam & headsite makes it fun, but it’s not absolutely necessary.
