That's the thing though, they wouldn't be killing off anything except the $500 sensor shell. A DSLR is literally a lens platform. Let apple sell the razor, they can continue selling razorblades. Sell a "case" that holds and attaches lenses for a hundred bucks or so, bundle it with an app, and allow people to continue using the same lenses, which they make more money on anyway. Commercially, this would be a huge win for whichever of the camera giants decides to do this first. Additionally, under this model, the cost of the phone + case ($800 + $100) is higher than the cost of the DSLR sensor by itself (which runs about $600 new), so it doesn't necessarily make it obsolete, but it gives iPhone owners a lower barrier to entry for DSLR lenses, which I would imagine would drive lens sales quite a bit. I really don't see a downside here, if it's possible on a technical basis
