Who knows? 6D was the main camera for many (myself included) and a backup camera for many others. I didn't had any problems with my memory cards (not a sigle memory card fail) and I hope I will never have a problem with memory cards. I use SanDisk Extreme PRO memory cards.
I know that some people think that a second memory card is absolutely necesary, but looking at all professional photographers that switched to Sony, Fuji, Olympus from their DSLR cameras... Sony A7R II is a 2700$ camera, with just a single memory card slot, just to give you an example.
