Just gonna throw this out there. This is total speculation on my part. But while checking out various concept illustrations of the new Avalon Mall expansion, one pic seem to feature a big book store facade. I realize the concepts drawings are only concepts but perhaps Crombie Properties are trying to whoo Chapters/Indigo to move down to the new mall expansion area. It would be a pretty good anchor along with the Winners store moving there too. Crombie REIT already owns the land right up to Chapters so this would not be that far fetched if they offered to purchase the current Chapters store building.
Here is the concept drawing of the book store at the mall.
