I think that's right for most people, but...
In the next 48 hours a nature magazine's editorial crew is going to decide to use my bobcat photo for their fall cover or use someone else's. It's an extreme crop on the far left side of the frame, perhaps 8-10 percent of the pixels to cover an 8.5 x 11 inch area. When these things happen (and in wildlife, they do quite a lot), an increase in resolution by 30 percent to 60 mp would be many times more effective than a dynamic range boost of two stops; of missing two bits of file information; etc.
I recognize most people won't have that need, but for those of us who do, I'd like Canon to be a brand we can rely on through the generations of cameras to stay on top of our competition.
The jerk competing against me (actually a super-nice guy) for this cover shoots a Nikon. I've resorted to doubling the pixels in Lightroom to make his advantage less obvious. Mine has a much better composition and soul, but, you know, editorial people will make the strangest decisions, especially these days when they ditched the photo editor and those calls are made by the random liberal arts graduate scribes filtering through.
