Here's hoping, though I doubt the current owner really intends to sell; this is just a stunt to look good on advice from their lawyer's PR campaign. I hate to be a downer, but I suspect that any serious offers would be reasonable, and yet those reasonable offers will be refused...
My expectations are tempered for the time being, but it's nice to see the buzz in this thread lately. Lots of great ideas here. That's part of what makes Edmonton interesting and unique - it's a city that's always been full of potential. The resulting inspiration from this constant state of possibility is endlessly appealing.
