Even then I have heard that not everyone could repro this and that Canon plans to release a fix soon. I have also heard that other cameras (including Nikons) exhibit this behavior to varying degrees. Some people just have too much time on their hands and have unrealistic expectations.

Check for 'black dots' on the 'Underexposed' blog of www.news.com portal. It's one of the last posts. I don’t know if you are aware of a problem that plagues the 5D Mark II camera.
