That's surprising, Gangster, considering the Apple Store near me has three remaining in stock (I'm thinking about buying one, which is why I know). You would think that Apple would have just shipped you one from a store. If you search with Google for part number M9555LL/A, you will probably find someone who still has one in stock.
In any case, I lament the loss of the single processor Power Mac. I know that it is not as sexy as the dual units but they played an important role for those who want a tower but are well served by a single CPU.
