Guys, some hot/dead pixels are a fact of life, but it shouldn't bother you so much. Every camera sensor will suffer to certain degree (with that many millions of pixels, you're bound to get a few with some leakage), and it's usually only apparent when you have a black or near black background (or you're testing with your lens cap on). I've been regularly experiencing this with all my cameras (5DMk2, 7D, XTi, 40D, etc)
If they get permanently stuck, it's a little more annoying to look at, but I would just create a cloning brush preset in your editing software and batch apply to everything you import.
I know it hurts to realize that the camera which cost so much money could be experiencing such a "fundamental flaw", but I think we've all gotten used to demanding perfection from our equipment, sometimes we forget that we are already pushing boundaries of physics in many ways.
