Good news for some bad for others. You can no longer apply for AS Visa if you have an open AS Visa card. You have to close all of your AS Visa cards and wait 24 months from when they were cancelled to apply again.

So if you want to continue getting more than 1 companion cert per year, do not close your existing cards. Must be AS doing. I wonder if AS will be limiting purchase of miles at some point as well?
