Its called a "luxury" for a reason. If you can't afford it, don't buy it. Just don't whine and cry when the market prices the luxury out of your price range. Everybody gets what they want. Nintendo gets paid, the retailer gets paid, I get paid, and the guy willing to pay out the wazoo for the latest gadget gets what he wants. Everybody's happy, except for you, who will still cry and whine that I'm breaking some unwritten moral code about being fair. Guess what? Life's not fair. its not fair that there's going to be at most 5 million WiiUs by Christmas. Regardless of if I bought an extra or not, there'd be people who wouldn't get one. Not fair. Not fair.
Scarcity breeds value. I hold an item that is scarce (in the short run). It would be completely stupid NOT to sell it, and then rebuy the item when scarcity is no longer a problem at regular market value. If you have a problem with this, then I suggest you take some classes on economics, because THIS is what makes the world turn.
