Very few condos outside of the core utilize the podium rooftop and/or the tower rooftop for common areas. I believe that if you buy in a building that offers this you don't necessarily have to pay for the best view if you can enjoy it periodically in the common areas.
At the moment Charlie, Cinema, and 300 Front are the only three hi-rise towers being built in the entertainment district, but fasten your seat belts there will be 16 more to come. Can't wait to see this area in 5 years.
