They updated the club seating in the lower bowl - not sure if they'll do the upper level anytime soon it still seems okay to me. I'd assume the rest of the lowers would be next?
The Superdone was redone in phases as well.... I know the Superdome was club 300 level first, then lower 100 level club, then lower 100 level corners/ends. Not sure if/when Terrace will be redone - haven't been to a home Saints or Hornets game this year unfortunately but this is from observations on TV - I knew both stadiums intimately as I have/had season tickets for Saints/Hornets both for many years.
