I know a number of developers in Berlin who speak little German. That said: - If you go outside of Berlin, it will be harder - Even in Berlin, sometimes your baker, cab driver, etc. might not have a good command of English - dealing with authorities can be difficult (that one's even difficult if you know German because of the excessive legalese) Also, in the end, personally I think that if you want to live somewhere you should learn the language because otherwise it's kind of a shame (unless you don't plan to stay long). But you don't have to know it necessarily before moving there, and plenty of people here just stick to their expat bubbles...
