It seems like Google is preparing to host a top contributor meetup in Munich, Germany.
Moritz Tolxdorff from Google's Dublin office posted on Google+ a picture of the sign welcoming the top contributors to Munich.
Google's Top Contributors are volunteers who spend time in Google's forums answering questions for free.
Moritz wrote (using Google Translate):
Everything is ready for our top contributors and promoted in the product forums. Now only missing our guests of honor:-) # TCMeetups2014
Are you headed to the meetup?
Forum discussion at Google+.
