Do you speak from actual experience? Or just hearsay and "seeing numbers on the internet"?
I am asking because I have a K10D (and more modern cameras like the K-S1 and K-50) and it has enough information on a sunny day for shadows and light spots at ISO 100. First the dynamic range capture is not linear as with CMOS cameras - you already start with you shadows a bit lifted up. (I know this is a somewhat interesting topic where not a lot of data is available to us final users - and due to *all* sensors being non-linear to an extent, including CMOS - but I speak from experience, having shot CMOS and CCD cameras in similar conditions with the same lenses for years now).
On top of the CCD being more non-linear than CMOS and having more details in shadows without any adjustment to the RAW files, there's at least 2 stops of lifting that can be done easily from the shadows with CMOS. I get 3+ from my K-S1 and about 4 from my K-50, but on a sunny day I don't need all that.
The K10D was such an improvement to my lunch photo walks over the K20D that it replaced. With the K20D, lifting 1 stop of shadows on a sunny day made the shades fall apart. More than 1 stop was totally useless.
The only times when the CCD will not be able to lift as much as you'd need is on sunsets and sunrises when you do need those 3-4 stops to lift up the scene against the brighter sky.
Shooting at night is not a problem if you have fast lenses.
Here is a shot that gave me that "a-ha!" moment when I realized that I had more shadow detail out of the K10D out of the box. I didn't have to lift the shadows much. In fact I had at least another step of lifting available should I need it.
That kind of shot used to frustrate me with the K20D. Now with the K10D and with the K-S1/K-50 I don't have any issues. But with the latter two cameras I'd have to lift at least 2 stops from the shadows to get these same results.
Finally, as for print size, again, most people throwing numbers around don't speak from experience. These people (like Thom Hogan) who say you need *at least* 42mp to make a medium size print - I wonder if they ever print anything in their own lives. I researched the subject a while back and found some interesting comments from people like this one:
"I have large prints on my walls from 6mp, 12mp, 16mp, and 24mp DX and full-frame cameras. You would be hard-pressed to tell which is which. But 24mp full frame files definitely take up more storage space." - source: comment section of

I remember seeing another comment - which I can't find now - by someone who worked at a print shop and they had several poster-sized prints on the wall, and *nobody* could tell the 6MP files apart from the 24MP and so forth. They all looked just as sharp unless you took a magnifying glass to them. So, any of you who walk around with a magnifying glass in your pocket to look at other people's prints, I'm sorry to say this but, you really need to get a life
