I am also betting that this will take some time. I am reviewing what happened with Oracle's hostile takeover of BEA systems and I am seeing a interesting pattern. That after the euphoria of the initial offer, the stock tanked and then went to the negotiated price.
Look at this chart I got online - the tab KL is where the unsolicited offer was made. Notice the price after months of negations , then they approve the merger at point A.
