They probably could make a killer camera. But, DSLRs are pretty much dead. Canon and Nikon are both investing in mirrorless now and IIRC Canon has effectively stopped development of their SLR line. And the camera market in general isn't great - compact cameras have effectively been replaced by cell phones and mirrorless systems are largely a pro-sumer product. FWIW, I bought my iPhone Pro specifically to replace my second mirrorless body. I'll keep one body around for "real" photography. But the phone is good enough for random snapshots.
