why not f/1.2 by Sony?

An 85mm/1.4 would be pretty expensive and massive

Why doesn't Sony use smaller sensor surface advantage from NEX system to build f/1.2 35mm lens,  and 85mm f/1.4?

Canon makes an 85mm F/1.2 lens right now and I suspect an E-mount version would be even longer simply to take up the shorter flange distance.  The E-mount version would likely be just as large a diameter as the huge Canon lens just to accommodate a 71mm diameter aperture.  I'm not saying it's not a useful lens, but I'm not sure what this "smaller sensor" advantage is you're talking about.

The existing 35/1.8 seems pretty close to an F/1.2 version, so the issue for Sony there might just be that use-case is pretty well served already.
