My experience with Burg has mostly been that if you drink them too young there is little downside, they still show a great deal. With Bordeaux and Cab, though, I am really loathe to open them until I am reasonably sure they are "ready."
So, with Burg, I have a hard time waiting because I can be pretty sure I won't have a bad experience. My experience with the '05s though has been universal: none of them are ready, even at the village level. I leave to others to say whether they will ever come around.
