To me this is all very simple:
The 6D seems like a fine camera for FF beginners. The problem is it should be about $1600, have a flipscreen, aimed at the video group, and fall in the xxD line, something like a 65D. Gimmicks like WiFi and GPS can remain (yes they are gimmicks, although useful for many, they are not core camera components).
For us that care more about core components like AF, view finder size, build and ergo, and even card type there is only 1 option which is the the very costly 5D3. Now that Canon has offered an xD alternative to the 5D3, there is little to no hope that Canon will offer a mid range FF body this cycle.
I think we can all agree there is a huge gap between the 5D3 and 6D. If the 6D was a xxD and the 6D was in-line with other xD (single digit) bodies, it would be good for us and good for Canon. I think there is plenty of room for a another $2500 FF body assuming the 6D is a xxD priced about $1600
For those telling us we are too cheap and unwilling to cough up the bucks for a 5D3, well, even in the year 2012 $3500 is a lot of money for a body and difficult to justify for many. Some just don't have it, others can't justify it. Canon will still likely get our money but in the form of glass and accessories so its not about being cheap.
For those telling us to run to Nikon, yes some will and have. For myself, I'm invested in Canon, I'm staying with Canon for several reasons.
I certainly understand Canon-F1's frustration and desire to send Canon a letter although I don't think it would be effective. Yes there are bigger issues in the world as one poster mentioned but that is partly why I visit CR to escape much of the BS in the world. Finally I think it is perfectly appropriate for someone to express their frustration or disappointment in a product spec or announcement as long as it's in moderation and appropriately stated.
