I'll throw in my 5D's worth then :D I think they will sell these by the shed load - already heard of several people pre-ordering. It will make an ideal back up camera body for those who already have 1D cameras who at present have to buy a second 1D or else cope with the crop factor of smaller sensors. So that's the wedding photographers taken care of then, they have to have back up cameras as do most other professionals where they cannot risk losing the shots for the sake of not having a second camera body. Lots of people have not switched to digital yet because they would not compromise on having the smaller sensor, especially if they already have lenses designed for 35mm. But lets face it though I can see it being very popular with professionals it is clearly aimed at the amateur market. There have been people just dreaming of having a full frame digital camera and it has just come within reach of many. I don't think the pixel count is that relevant to these people after all it is the same pixel density as 20D, just because the sensor is larger it has more. What they want is the full frame to use their existing lenses and retain the wide angle capability for landscapes etc. Nice to see it has spot metering too. I think Ryno is referring to the viewfinder being brighter because the mirror and prism are larger for a full frame. The smaller size sensor cameras have the advantage of speed and crop factor for the nature and sports enthusiasts and with current sensor quality issues they will remain significantly cheaper, so don't see as this camera will challenge their market, it is aimed at different people. As devious mouse has rightly pointed out the biggest variable in any photograph is the photographer.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
