To me, this shows who is the real competitor for Canon. From the beginning, this was the main idea. Both camera makers (Canon / Sony) have their own line of sensors, R&D, industrial power etc. But the first part is crucial. Canon was / is just lazy, and satisfied with the $$$, but, I think, they can switch to "war mode" soon. Their latest products are showing signs of that. Sony knows (obviously), and it seems they are doing everything they can to exploit the momentum. Canon cameras MIGHT be considered inferior, but that "inferiority" has a tiny margin in real life, and it is related mainly to sensors. On the other hand, it is hard to match Canon's lenses lineup, and this level things. However, however, once that sensor matter is improved...photographers will benefit even more. IMHO
