do you project a turnaround right now? Looking at their current product base I would say "hell no!". Microsoft has nothing up and coming to convince me they will gain more search users. Each and every time they have unveiled a new search or online tool they have failed to capture the market. I do not see what will be different in the future once they come up with their next big idea. Bing is clearly not going to take over even with it being the default in internet explorer.
So what about the recent Facebook integration, still rolling out and the overall switch to social search, something Google can't get right no matter how many companies they buy.
What about the only very recent Yahoo integration, the Windows Phone integration and the constant improvement with maps beyond what Google have offered.
