Actually, they are not necessarily contradictory. Canon clearly did NOT stop innovating in sensor tech. Canon has been "continuously improving their stuff", including their sensors. And, we have seen significantly improved sensors, just not in the same direction as Sony.
I have a hard time counting on-chip autofocus as an actual improvement in the sensor itself.
But yes, Canon has indeed made minor improvements to their sensors, mainly with respect to eliminating the artifacts, such as pattern noise, that shouldn't have been there in the first place (though it shouldn't have been there in the first place, it's sometimes better to release what you've got than to perfect it first, and that is likely the case here. Getting out all the bugs is a time-consuming endeavor).
Even so, the pace of development of the sensor itself is clearly substantially reduced compared with other firms. Also, I was under the impression that other companies were managing to produce greater dynamic range without making use of Sony's patents in the process, but I could be mistaken about that (and, thus far, the only thing I've found that even comes close is Leica's M-240).
If you read this board a lot, you would think the entire photographic industry revolves around DR. Canon was clearly pursuing improvements in video performance in their sensor tech. Was that a good approach for their business? Time will tell.
I know that Canon has been concentrating on video, but aside from the on-chip phase-detection autofocus, it's not clear to me what else they've been doing with their sensors to improve them for video purposes that wouldn't have a direct and beneficial impact on still photography.
Not every R&D group gets the same ideas, so someone will have a better idea. This says nothing about spending nor about the effort to improve the product. Clearly, Canon could not engineer their way around the Sony patents. Neither could Nikon. Nikon chose to join rather than fight. Canon's innovations have not achieved the improvements in DR that Sony's innovations achieved (Nikon R&D gets no credit this, but the company does for having the business sense to license the sensors). The improvement in DR led to the higher density senors, it seems to me.
There was quite a bit of speculation some time ago that Canon was being held up by their fab and by unwillingness to invest in a newer one. I suspect that still rings true.
