The new runway is due to capacity issues.
The length of the runway is due to the elevation of Calgary above sea level, plus the takeoff lengths required for the largest potential aircraft at that sea level.
So, while we may not see more 747s/A380s in the short term, there is potential to see more in the future, as the terminal and runway will be designed to be able to handle them. Future ridership numbers will determine what planes the airlines put on routes.
