Canon 400mm f/2.8 IS II is 11K. I think the reasonable price for Sigma 400mm should be about 6K if the IQ of it is close or equal to Canon version.
+1 but i think that for these big lenses the huge difference (beside the price) will be the weight (and hopfully not weather sealing). the Sigma lenses will be really heavier for sure...
