Microsoft (MSFT) and Yahoo! (YHOO) talk down deal in public

Anyone who did not think a Microsoft (NASDAQ:MSFT) buyout of Yahoo! (NASDAQ:YHOO) has become less likely should have stopped by the All Things Digital conference. According to Reuters, "Yahoo Inc Chief Executive Jerry Yang said on Wednesday a potential deal with Microsoft has tremendous power, but the software giant appears no longer interested in a full merger."

The leaves Yahoo! management, its board, and takeover artist Carl Icahn in a tough spot. Many analysts believe that without a deal, the Yahoo! shares could drop back near $20, where they traded before the offer from Redmond. Yahoo! currently changes hands at $27.

The news is a sign that Microsoft thinks it can do almost anything on its own, including challenging Google (NASDAQ:GOOG) in the search business. Gates, Ballmer & Co. have the money to get the engineering hands on board to push better search tech, but user loyalty to Google may be so great that even a much better product from Microsoft will not break its rival's hold on the market.

Microsoft has had success exceeding the market's expectations before. No one believed that the company's Xbox could challenge the Sony (NYSE:SNE) PlayStation franchise.

But, search engines are not game consoles and the rules in one game do not necessarily apply in another.
