Keeping up resale value is a huge part of maintaining brand image, and constant price-slashing will make your customers gun-shy. And the lack of technological progress is an issue for system cameras: why would you invest heavily in proprietary Fuji glass if its usefulness is tied to Fuji's whim and a 16Mp sensor? That's a risk that does not exist with DSLRs or Leicas. In the worst case, you can adapt DSLR and Leica lenses to anything mirrorless. Due in part to the short register and cropped format, you can't adapt Fuji X lenses to any other purpose. Don't like the processor-hogging X-Trans II files?* Tough cookies.
