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

There is no size advantage for a 85mm f1.4: it would be the same size for ff, APSc or M43, with the 35mm there might be a small advantage, particular because of the small flange distance of the mount, but I am no expert on this.

AFAIK, for 85mm from f2 onwards you can build smaller lenses for tele from APSc compared to ff, and FF APS and m43 f5.6 300mm tele are all the same size and weight.
