I think there's rightly some pessimism about the mall, however. Yes, we've gained Sports Authority, kept Saks and upgraded the Walgreens. However, we've also lost Gap, Jos. A Bank, and two restaurants (Mesa and Vincent). So overall in the past 2 years we're -1 clothing retailer and down two restaurants. Getting a Nordstrom's would be huge to at least get us back to even on one important category, so I really hope that pans out.
For what it's worth, if you're riding down the escalator in IDS center you can occasionally see into the old GAP space over the window covers. I've definitely seen the lights on once recently and people milling around, so it's not completely dead.
