It's mainly younger people who make online things successful. If and when they decide that Bing is trendier than Google then they will use it and spread the word. That could be when "it happens".

The young and trendies are more likely to get excited by social-networking search than by traditional search engines. Bing is merely a Royal Crown to Google's Coke, or a Hunt's Ketchup to Google's Heinz. It isn't hip or trendy; it's just a less popular version of the brand leader in different packaging.
