I personally sold three Arcades shortly after the price cut went into effect at our store (within the next three days, while we usually sell one a week, if that).
However, they were all bought by people replacing their Pros. :S
I also sold an Elite. The idiot was spending an extra $100 on what is nothing more than a black coat of paint and a larger HDD, yet he was asking me about used controller and game prices. If you're that worried about money, why the hell are you getting an Elite? xD
