I lean towards your outlook, Citrati! Missling would have to have been STUPID not to sell all of his latest options and keep a little less than half had he been convinced that he would not get at least a conditional approval, what Investor said is probably correct when considering the "normal thinking", but Missling has a confidence that we have to assume is on the right track.
He owns more shares than anyone else who blabs here!
I would have EXERCISED and SOLD ALL SHARES if I did not have extreme confidence which I think he does have, he bets LARGE.
