"the other possibility is that Lanza killed the buy-out, RM and Barry have left, and so there is no one else to step-up but Lanza. That would be a simpler explanation. Perhaps Lanza's interest don't aligm with BD."
Not exactly so. RM and all other board members have resigned to aid the rumored buyout. There is a block of "Super voting perf. stock" that out voltes all other stock. The person with that block can put anyone in charge. And has put in Lanza, at his wishes of course. Who owns the super voting perf., get to him and Lanza is out.
