If really soon is defined as the end of the month, and you add in the 10-12 weeks it takes from shiny silicon pizzas in to pin laden chunks out, that would mean parts are available at the beginning of May.
It would not surprise me if it is trading yield out for time to market, so let's add a month before they are really available. That puts things at early June for volume, or when AMD said it would have it out. Minor miracles do happen. µ
