I've heard from some that banding in 7d and 5d might be caused by IF and therefore while it might partly be attributed to QC it is also attributed to primary location of the photographer. If in fact IF is the (partial) cause then perhaps the cameras could use better shielding but I'm unsure how much can be done here after all the sensor needs to be exposed when you take the picture.

Low ISO noise and banding is not apparent on every 7D sensor. It varies from one copy to another, thanks to Canon QC. I have pixel peeped images from a few copies and they are all free from low ISO noise and banding. Also, I am very confident the 550D sensor will be free from such problems simply because it has two channel output (lower frame rate) instead of four.
If you want to compare RAW images from 10D, 20D... to 70D including D100, D200 and D300, take a look at [url="http://pixinfo.com/cikkek/dslr_evolution.3"]this Hungarian site[/url]. It contains the most comprehensive results. At the pixel level, the 7D is NOT in anyway inferior to the 20D. At the image level, it beats out everything else.
The remaining complaints come from (i) people who believe in the megapixel myth without any real experience whatsoever with the cameras (ii) trolls and green-eyed monsters. Wait till Nikon update their D90 and D5000 sensors with more pixels... these myths will die quickly and silently.
