It is funny how "normal" silence creates conspiracy theories! Have you ever closed on a house? It often takes much longer to close a typical house purchase than one expects. Now, multiply the complexity by 1000× and consider the non-typical nature of this deal - and voila! Unexpected delays due to lawyering, lawyering and more lawyering back-and-forth.
A buyout offer would be material news and required by law to be PRed. Please keep the rumour mill boarded up.
