Meh... AMD was ramped up production on AM2 back in Feb/Mar. They spent a lot of time making parts so there wouldn't be a shortage. AFAIK, Intel has only recently begun to make Core Duo's (desktop). Also, Core Duo production is like less than 35%.
But who knows, there may be plenty of them at launch. But when u consider the price of those bad boys, I wouldn't count on it.
