^ I would think the interest must be in the office and perhaps retail space... I'm not sure how they'd even gauge interest in the residences at this point. Have they even begun marketing that tower?
How about this? Keep the existing tower 1 and 2 heights, combine the Sutton Place hotel and condos into a 36-ish storey tower and then you free up space for another 20-ish storey office building next to it?
I'd prefer if they didn't add more retail space... that could encourage some potential tenants to consider Cityplace and the various skywalk CRUs.
