It's certainly possible. I suspect if Google drops out though, then the price for Bing being included would go way down. They'd have no big players to bid against. I don't see Yandex or Baidu being interested. It's also possible Microsoft would exercise caution, considering this suit against Google. They may want to sidestep any deals that could paint a target on their back in the future.
