It's worth remembering that the guy spoke in very hypothetical terms. There is no prophecy of doom, although maybe a little enjoyment in seeing the market segment that jeopardized them being jeopardized in return.
However, even 1 year ago, when DSLR market was growing double-digit year-to-year, nobody would have imagined what happened this year. Consumer electronics is an ever volatile market.
As somebody mentioned before, film is not dead - Leica still has around 650 order a year. It has however become a real niche market, and the possibility that one day DSLR will be the same is not to be discarded. How many people, after all, invest in 300mm f/2.8 and the like? The whole world goes towards portability, networking and software functionality; something smartphones are teaching the hard way to camera manufacturers.
