New 35/2 IS beats MTF of 35/1.4L

Although a stop slower, the new lens beats the old L by a good margin in both microcontrst (thick lines) and sharpness (fine lines). Aside from a stop difference and weather sealing, is the L becoming obsolete? Plus the new one has IS, better coating, and better AF on 2012 bodies. Does this mean the L version also should be upgraded soon? Otherwise it doesn't seem to offer much in comparison anymore. Thoughts?
