(1) PRICE - everyone is once again underestimating what Canon may or may not charge for a 7D2 (if they ever get around to building one). The Canon Marketing executive interviewed by Gordan Laing of CameraLabs @ Photokina, desperately went out of his way to say that although the 6D fits in the numerical range between the 7D and 5D it is NOT a linear product positioning....what does he mean by this? He means the $2099 6D got the '6' designation because it is FF, but he qualified his remarks by stating that it was in essence a FF 60D (for amateurs). This my friends leaves the door wide open for Canon to introduce a 7D mark II for Semi-Professionals (Pro's & serious enthusiasts) and price it significantly above the new 6D. The strict linear interpretation would dictate that in terms of price: 1D > 5D > 7D , however, what Canon employee said indirectly was 6D > 7D does not necessarily have to hold true. Why else would he go to such lengths to stress that 6D is not the same as other xD designations.
(2) FEATURES - everyone wants more DR, better ISO & low-light performance, dual memory cards etc. and are willing to sacrifice MP, accessory features like GPS + WiFi, because most of you already own a Canon DSLR which does not have this whizzy new features (so you won't miss what you've never had) and you wish that your current camera body had better IQ. Canon on the other hand, want to sell new cameras, not just to you guys (existing customers) but to new customers as well, so <18MP is a non-runner as is not having WiFi etc.
Wanting more (IQ) for less (money) does not compute for Canon -> they'll happily sell you a 1DX
