From what the op said, it doesn't sound like a full remodel. Electronics is probably the Electronics Experience expansion. Front end sounds like integrated guest service. Pharmacy will probably be updated, new counters, new paint. A store near me is getting the furniture expansion which has a layout similar to the rear seasonal patio set with collection displays in a open area. Seems like a store by store basis on who will get what. Some stores are also getting expanded infants area.
A full remodel usually involves updating, resetting the entire store, and sometimes moving entire departments, over a 3-4 month period. While this will be done overnight I doubt it will be of that length.
