I think it's a given that it will be better than Wembley for atmosphere. As spectacular as the new stadium looks, they've also taken atmosphere into account and that huge single-tier end is a great move in that respect.
We can only hope. The big unknown is the fans, though - will the right types to create an atmosphere be in that stand or will it be half full of types who only open their mouths to tell others to "siddown"?
