Just to play the devil's advocate here in terms of price/performance, let's assume the new Zeiss is able to outresolve the highest resolution Canon sensor, the 5D Mark III. If we trust DxO's measurements, there is only one lens that currently outresolves the 5D III sensor, the 300mm f/2.8L IS II USM, which retails for $7,299. It has autofocus, IS, and a fancy lens case.
Assuming the Zeiss 55 is of similar build quality, comes with some kind of fancy case, and is manufactured at a much smaller scale, the price doesn't seem entirely outrageous. All other factors aside, it costs more to make far fewer lenses than it does for volume production and Germany is typically more expensive than Japan.
I hope the lens turns out to be amazing - anything that will motivate other manufacturers to compete is a good thing.
