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 aren't technical difficulties making those lenses, they already exist in FF equivalent, except the E-mount bodies, they are too small, weak, and uncomfortable for large lenses. The 85mm/1.4 would be heavy (likely about 1.5lb) for small NEX cameras. Rumors say that Sony is heading with larger mirrorless designs using A-mount. That makes sense, especially since the future sensors will be FF.

A 35mm/1.2 lens would be no problem on any NEX body.  I personally think an 85/1.4 lens would also be fine on the NEX6 or 7.  Much longer than that and it might be beneficial for Sony to make a slightly larger NEX body for the high end.  But this would be for ergonomics, not strength.  The E-mount itself is as mechanically strong as any on the market.
