NOBODY is going to "bid" for Yahoo. Ever. Not after the Microsoft fiasco. Given the new board, I could see them accept a negotiated offer at the right price but with a new CEO, I think that is some time away.
My guess is still that the only way to acquire Yahoo is with an unfriendly tender, but given the track record, lack of vision, incompetent managemen and questionable future, it is hard to see who would buy it.
