I'm not worried about BD performance at launch at all. It will competetive in performance and price. But the high clock design could mean that AMD is hitting a performance ceiling pretty soon. How much further can they take the stock speeds? 5Ghz turbo? At one point they will have to start adding power through extra cache or improvements of the core itself. We know that a 2nd and 3rd generation BD are being prepared but it will be interesting to see what road they are going to take there. What we don't want is 4-5 years of AMD on the same arch with not much room for growth.
