I found a calculator. Turns out 135 has less DOF then 105. Could mean nicer bokeh. We'll see.
Depth of field is relative to max aperture diameter and focus distance, so it's likely that you'll get very similar background blur with more depth of field but more compression from the 135 with the same framing, as you'll be further away.
105mm/1.4 = 75mm
135mm/1.8 = 75mm
The max aperture diameter/entrance pupil diameter is actually the same between the two, so Nikon's 105/1.4E actually makes a bit of sense, as the natural working distance (based on field of view) of the 105 is going to be a little less than a 135, weight is going to be a little lower, size is going to be a little lower, and the lens will be a little more accessible to DX shooters while not losing much if anything to a fast 135.
