Canon is a publicly traded company, so their priority is always maximizing shareholder value…and for better or worse, shareholders tend to prioritize short-term value/growth over long-term strategies.
Particularly true of Wall Street investors and companies, not so true of Kikkei investors and companies. It has been said for decades that Japanese companies were much more long term oriented than US (I will admit to not having kept up to date with more recent times, and what motivates the Japanese today.)
From a product standpoint I can also understand why Canon positioned the EOS R the way they did, and why decisions like the lack of a second card slot were likely intentional. They need to be careful about positioning their mirrorless cameras as products that buy in addition to DSLR’s, not as a replacement to DSLR’s. Cannibalized sales will add nothing to the top-line, but they’ve double downed on their fixed and variable costs brining a second product line to market. I think this will be the case for at least the next couple of years, though the lenes signal what the long-term vision is.
Very good observation about adding costs without necessarily improving the bottom line, if cannibalization occurs. We already have seen the affect on bottom line with the lowered margins of successful 6D vs. the 5DIII, and so much of the POTN readers being disappointed by the 6DII, and failing to understand Canon's need not to cannibalize 5Dn sales again by too good of a cheaper product.
