Google+, a threat to facebook?

As google release their own social jetworking website to the public, are facebook biting their nails in anticipation of whether the fans will still put money in Mark Zukerberg's pocket leave him scrambling for words like bebo.
        Google+ is a simple and easy to use network that lets ou chat with friends and keep up with the latest social updates, just as facebook has been doing for the last 5 years or so, however, google+ is eager to grow and make it's mark whilst Facebook are constantly changing much to the annoyance of the followers. Are we ready to desert Facebook and join a new league of young webpage designers? Has Facebook had it's time? Above all is this just a mere cycle, when a new site comes along will we join them and leave Google+ floundering?
