I am pretty sure that Eisner second only to Roy in ownership, according to Dow Jones News Service. No matter neither has enough to control the board by himself.
Large institutional investors will look at who will do the best in the future, in a thriving economy. For better or for worse, I wont give my opinion, Eisner did a great job when the economy was thriving. Kind of like the Pres of the US, if the economy is good he is popular, if it is bad he is the devil.
He has made some bad decisions, in hindsight, but if not for one ill fated heliocopter flight I think he would still be thriving, IMHO
