Is there any evidence to suggest that down-sampling a large image will increase sharpness and reduce noise? A lot of people have been critical of the number of pixels crammed into the new Canon 7D. I noticed that the specs list an m-RAW setting with the same pixel dimensions as the 40D. Will the down-sampled m-RAW image (assuming all other things equal) be any sharper or "cleaner" than the native 40D image?

I don't think there's any point in speculating before testing. "A lot of people have been critical of the number of pixels crammed into the new Canon 7D" - and I'd venture to say that none of them have ever even seen a 7D, nevermind actually used and tested it. |

Like Bob mentioned, 99.99% of the people hammering the quality of the 7D picture have never seen one, yet they are proclaiming serious noise and other issues with the pictures.
Several review sites (including here, I hope) will have reviews out to wade through soon.

I will be reviewing the 7D, probably sometime this month. I don't know when I'll be able to get my hands on one yet!
I'd be very surprised if there's any sort of serious noise issue. I have no doubt that if you look closely enough at high ISO images you will be able to see noise, and at ISO 12800 it will probably be pretty bad. However that's par for the course. Push any DSLR hard enough and the image quality will suffer.
Every camera has its own set of problems or "things that could be better", so complaints should be taken with that in mind, especialy when they come from people who have never even seen the camera. Some people just look for things to complain about
