Sure, but then you also lose the ISO improvements over crop if you increase the density of a FF, eliminating one of the core desired attributes of FF.
That's a misconception. The ISO benefits are not due to larger photosite size, but larger total sensor size. With more pixels, each individual pixel is noisier, but the total noise level remains the same. Cut the sensor area down by 2.25 or 2.56, though, and you lose one-and-a-half stops or so of ISO performance.
Also the 7D is a crop and is used by many professionals, including wedding photographers. The 1D series (non-S) was crop, and it also was used by professionals. I just don't buy the "FF is what pros use". Get the right body coupled with the right lenses and put it into capable hands, and the results will speak for themselves, whether 2.0 crop, 1.6 crop, 1.3 crop, or 35mm equivalent.
That was five years ago, when full-frame sensors were still very expensive and cameras had bandwidth problems trying to shoot high-resolution images at fast frame rates. Times change and technology advances.
I've only ever seen the 7D used as a backup, and, even then, only by relatively low-level wedding photographers. Most prefer to have their primary and secondary cameras share the same crop factor, i.e. full frame.
Just remember FF is also a crop, for those that shoot medium and large format, so I suspect they are saying the same about FF shooters.
Except that medium-format cameras have nowhere near the functionality of full-frame cameras. Very poor lens selection (unless using a digital back, in which case you lose even more functionality), poor AF, minimal frame rate, poor performance at anything above ISO 100 (apart from the newest CMOS medium-format sensor from Sony), poor/nonexistent live view...
The same cannot be said for full frame vs crop sensors.
Also there are 4 differently sized APS-C crop bodies, the 7D is actually nearly identical to the 5D2 in size and weight. It also debuted at the $1700 price point USD when it came out.
Because the $2500 5D2 was out of reach of many people at that stage.
Nowadays, you can get a full-frame body for $1500. There's not much room for anything more than entry-level and mid-range crop bodies below that.
yet here we are, with larger more capable APS-C bodies. I doubt Canon made a marketing mistake when they broke the xxD line into 2 directions, during the announcement of the 7D. I suspect they plan on keeping with that plan, with the 7D series adding more capability and performance over the xxD, xxxD, and xxxD lines. This will continue for as long as the competition does the same, as well, so the direction of Sony, Nikon, and Canon will feed each other.
There hasn't been a pro-level APS-C body released by anyone for the past five years. There have been countless entry- and mid-level APS-C bodies released during that time, and a lot of pro-level (5D3, D800, 1Dx, D4, etc.) and mid-level (D600, 6D) full-frame bodies in the same time. If there was any room in the market for an APS-C body with pro features, outside of the wishful thinking of a few enthusiasts who don't want to part with their crop-format lenses, they would have released one by now.
