The posted site is the confirmed (by personal investigation and by the mall security personnel) site of the upcoming Apple store. (in the former "Gap Kids" location; south side ground level, kitty-corner from the new flashy "Bose" stereo store, and also Lego-land, and directly across from the new oversized "Gap Kids" store (opened 4/25/01)) It will be next to a "Discovery Channel" science store.
All other upcoming mall stores, usually post the store name and sometimes other information on the white placards that Apple has left blank, and there are usually some gaps in the placards that are easier to see through.
The renovation is probably just now starting, since the old store there closed only about a week ago. The security personnel informed us that stores usually open within about 2 months of design work starting.
The Apple store will actually combine 2 locations "S132 and S136" to create an "oversize" store as well.
While there is no official word of Apple retail stores as of yet, it seems inevitable. You can find more information about Apple at their Web site, and see the pictures of the potential future location of one of Appleis stores at the Apple/Mall of America Web site.
