Frankly, no dedicated camera is ever going to win back users with software features, and it is extremely unlikely that Canon or Nikon could out compete Apple and Google in this area. It makes much more sense for Canon to continue to serve hobbyists and pros with features that phones cannot offer, rather than trying to complete on software.
Maybe they're working on something big, but Canon, et al. to me appear to be headed the way of Kodak, at least in the consumer market.
They would have a hard enough time with casual users just because the camera on their phone is "free" (included in the price and perhaps more importantly, the form factor). But I don't even see any attempt to compete with Apple or Android cameras.
I use a full-frame SLR, and love my lenses. But I put it at even money whether I will ever buy another.
