Not concerned at all.
And in fact even after 2 years, the 5D still doesn't have competition.
FF sensor in a Crop body? Doesn't exist.
Compared to the 40D's 6.5fps, the 5D is pretty "slow", but it was never meant for that type of shooting. (there's the MKIII for that!)
That said, I am very excited about the 40D. I should get it this week!
There is no reason for 5D owners to be upset regardless of outcome. The 5D was a true masterpiece, but it is a 2-year-old masterpiece. Digital imagery is a moving target like many other semiconductor-based technologies.
I am not saying the 40D makes better images than the 5D. We need a lot more evidence. But, if it turns out to be true, it would make sense. No one should be shocked.
. Hmmm
