From what I can tell, he said he got a shipment in. I know you can't buy more than one Xbox360 at a time at stores, so I'm guessing he manages/owns/works in a game store. As such, I believe Microsoft has set the retail prices for the systems, and I'm sure they'd be very interested to know that one of their retailers was charging so much, in fact, almost 4x the actual cost of the system.
On a side note, I have an Xbox360 and it's awsome, and I'd probably pay $1000, but no more. In fact, just dropped another $200 today on 3 more controllers and 3 headsets. I'm planning on getting a nice remote next to go with the whole setup. For Xmas, my roommate is getting a HD projector, and we already have 7.2 surround sound, so the Xbox360 is the piece de' resistance. I'll probably also get a PS3, or he will, when they come out in '06.
