Ok. Yeah I understand its probably impossible for anyone to know exactly, but is it more like a month or two or a matter of days?
If they go, they'll be back. Understand what happens... Apple releases a computer and starts selling it. They start getting returns and other units come back to them for a variety of reasons almost immediately. They have to tool up and get their refurb plant running. Once the refurb plant has enough units to make it worth adding the model to the refurb store, they start selling them. But once they reach that point, within the limits of normal ebbs and flows, there will be a continual flow of that model into the refurb stream as long as it is being sold new, right?
What that means is that if they sell out, in a week or two, there'll be more of them.... Just keep your eyes out, because they may again sell out temporarily. But if you keep your eye on the store, you'll get your MBP.
