Fantastic wiki and thread. Well done.
At quick glance it doesn't seem there is much of a net change in pax capacity across the fleet in coming years which suggests either that AC feels they have saturated the various markets, or they fly many aircraft not full.
I am disappointed in the change from A32Xs to 7M8s. It isn't new news of course but this thread serves as the reminder.
I actually have never liked A32X aircraft owing almost entirely to the engines. The sound they make on takeoff until cruising altitude is like nails on a chalkboard to me. Having said that, a few flights aboard the 7M8 have served as a reminder to be careful what one wishes for.
