Canon Inc is lovin' it .... they know we all need/want at least 2 camera bodies so we can take advantages of certain features for landscape/portraits vs sports/wildlife.

If they wanted to, I would think they could offer a 45 mp full frame sensor with in camera 1.3 or 1.6 crop mode and the greatest AF, fast frame rate performance features as well as dual cards, wireless transmitter, GPS, in camera HDR etc etc....you know, a universal, one size fits all, professional image capturing machine.

But then they couldn't sell everyone multiple bodies and external widgets
