If I remember correctly, the Roundabout production in '04 (?) was pretty stripped down, wasn't it? It seems like a show that just does well when not very elaborate, so I doubt whatever John is going to do with it will be radically upsetting, even to his detractors.
Also, on some level, almost everything Sondheim writes is about people not connecting with each other. So ok, you may hate the "walking patterns," as a way of showing that, but I do think one of the reasons John is such a great interpreter of Sondheim is that he stages it in interesting/sad/unexpected ways that extend past, say, walking around a diamond.
