Before the latest expansion plans were finalized, Populous provided a 20-year expansion plan below with the South endzone filled in. Also, in searching for this pic the other day, I saw an aerial rendering of the current 3-sided DWS with a Hard Rock Stadium-type roof (in Miami where they just had the Super Bowl) over each side. It looked awesome but I can't find it today.
