The mall itself is called The Shops at Anaheim GardenWalk. It's not all the individual shops that are being foreclosed upon. So my interpretation of the article in the link Bumbershoot posted is that it will pretty much be business as usual at Garden Walk while the auction is happening and beyond, minus the couple of stores that have vacated due to their own financial difficulty. Otherwise, all the other shops/stores are still there, as well as the restaurants.
By the way, didn't GW add in a Lush store fairly recently? See, for those of us who love us some fresh, fragrant anf fruity bath and body products, that is big news, because Lush doesn't have that many stores around town. I was even planning to try to make a trip to Lush on one of my next DLR trips (just like the Basin store is a big hit for me at Downtown Disney!). LOOOOOVE me some bath bombs and shower gel! I think Lush will still be there when I get there later this year. I think most of the stores will still be there.
