Doing so would undermine their own 35/1.4 so I doubt this will happen. If I were to guess, a 28/1.4 and 85/1.4 are more likely as the 28/2 has its limitations and the 85/1.4 wasn't the most corrected to begin with.

The most important characteristic of the Z* 35/1.4 is the OOF rendering at a bit of distance, in my opinion. I highly doubt that there are any other 35 mm lenses that could do this:
I don't even know if there are medium format lenses with the same AOV and equal DOF possibilities that does better in this respect. Of course they will most likely be sharper wide open, but the Zeiss does very well except for some purple fringing.
And a couple of them appear to have a swirly type of distortion. The centre is creamy smooth, but the edges are in focus. So it looks like it's very distorted here...
Thanks for the link. This shot at f1.4 is a good bokeh test with the b&w checkered coat and wall background. Very good, no nervousness here. Yes, there looks like some FC affecting the corners but pretty amazing overall performance, IMO. http://pliki.optyczne.pl/zei55/zei55_fot05.JPG

There is probably some FC but I think we're also seeing the natural increase of DOF towards the corners. IIRC that's caused by optical vignetting which also causes the cat's eye effect (smaller/cut off blur discs towards the corners).

By the numbers, yes. However, the 50 Lux-M ASPH has sublime rendering, and it is not clear which of these two lenses will actually give nicer photos. It probably depends a lot on the subject. And the Leica is of course 1/10th of the size (approximately).
On the d3x it doesn't look that different from the 50MP resolution wise.
I mean, sure the number are better, but the 50MP has great resolution in the center at f/2 (and in most cases your don't need that much resolution in the corner wide open), and by f/8 I'm not sure the resolution difference between the two makes any practical difference on a 24mpix sensor.

I think the main difference will be at f2.8 and lower.
Not so much at f5.6 or greater.
