You beat me to this post. I see no compelling reason for a Great Council of the Church and would prefer that this not occur. There are no grave theological issues of the sort that necessitated the previous nine councils. This seems like an invitation for trouble. The only upside is that as long as the Russians are there I am fairly certain that nothing too crazy will go through.
I guess one could say that I have very low expectations for the Council and will be pleased if everyone sleeps through the whole thing.
