That's a funny way of looking at it. First of all, almost all change is incremental, but that doesn't mean it is insignifcant. If reducing things to percentage increase was a valid way of comparing things, then someone who went from bench pressing 460 lbs from 360 lbs shouldn't be any prouder of the accomplishment than someone who went from 60 lbs to 76 lbs. It's just a funny way to make comparisons, unless you are trying to purposely minimize accomplishment.
I don't know a lot about sensor manufacturing (particularly Sony's way) but I don't think it is a stretch to say that sensors with smaller photosites are more challenging to manufacture than those with larger photosites. I haven't checked Larry's math, but it wouldn't surprise me if Sony first perfected their technique on an APS-C sized sensor before applying that same process to a larger sized sensor. I also don't think it is a stretch to say that once they have conquered that they might consider trying it on a "medium format" sensor. (Anybody do that math on what that might be?) All of that output required an imaging engine that can handle it, but we've seen that the latest can handle the 51MP filesizes of the 645z, so is should n't be surprising to see the smaller (than medium format) sensor sizes pushing the envelope to fill that range.
