the prices of DX bodies and lenses will plummet with everyone moving to FX.
I totally disagree. Canon has had Full frame since before there was a D70. What percent of their DSLR sales are full frame?
Should a wildlife shooter replace his D300 and 200-400 f/4 with a D700 and 600mm? Size, weight and cost are huge factors with wildlife.
For my landscape work, do I sell my D300 and 12-24 and 17-55, and keep my 70-200, to do the same thing by picking up a D700, 17-35, 24-70 and a 300mm f/2.8 or f/4. This load is expensive and too heavy to carry around on my back when hiking. Also, my working distance for macro becomes a problem.
My point is simply this. DX is not going anywhere and should continue to dominate the DSLR market. Canon shooters already know this
