To top it off, Nikon is almost entirely dependent on Sony (for sensors) to get the type of DxO rankings that they get. Sure, they could buy from another manufacturer, but they would lose any edge they have over Canon if they did so. I've always hoped that Sony would eventually leave Nikon high and dry regarding sensors, so Nikon would have to fend for themselves.

What do I believe this all stems from? The problem with Nikon is they're smaller than any of these other big name manufacturers. They simply can't compete regarding R&D and QC. And it really shows. And what bothers me is that due to this unwarranted praise, Nikon actually takes away from manufacturers who are more competent.
