As of this evening, no serious alternative bids have emerged for Yahoo (NSDQ: YHOO), and any kind of Google-Yahoo deal would be thought to pass the anti-trust examination, reports WSJ. Yahoo has said that it will take its own sweet time reviewing the Microsoft (NSDQ: MSFT) offer. Even if a Google (NSDQ: GOOG) pact comes through, it would have to be in conjunction with a rival bid by another company, to allay any of these regulatory fears.
