Because he wants to.
It's his money. Let him use it any way he chooses. If he's willing to pay above retail to get what he wants and someone else isn't, more power to him. Obviously he really wants it more and has the means to obtain what he wants.
Most of us had the chance to get one of these when he went up for PO. The ones who missed out are going to have to hustle to get one. This happens all the time when there's a hot item that sells out. The haves have, and the wants want. We have seen this cycle in many threads of a sold out piece. The EX will become available in the aftermarket if peeps WL don't convert here. The next question is....how bad do they want it and how much are they willing to spend to get it? For those that decide the EX is too expensive, there are plenty of REGs available to them.
Having said all that, I hope everyone here that is on the WL for the EX converts.
