I agree with the person who asked for 'iconic' floodlights. If something quirky or at least a bit different can be achieved without breaking the bank then they should definitely go for it. I don't think York St style floodlights would look right with a new, sleek stadium, but perhaps something along the lines of Trent Bridge's circular style would suit.
I'm also surprised at the lack of dugouts; presumably when they talk about the teams using the stand itself they're talking about incorporating some kind of enclosed section? Off the top of my head, the only ground I can think of like that is.... errrm... Old Trafford! I'm sure some ground geeks can provide more examples though.
