This is interesting data. It would be cool to see a graph showing historical search rates.
I don't believe Bing is going to overtake Google just because Google already has a large infrastructure. It has Google adwords which is used by millions of people. Google is the industry leader and any sane marketer is not going to take his chances with an up and coming search engine when they can easily work with the already established Google.
Furthermore Google's main business is the search engine and tracking searches. Microsoft's business is operating systems. It is a simple problem of allocation of resources.
Google is going to win in the long run.
