Basically someone would have to be confident that BTC is going to increase again in value.
That "someone" would do far better buying BitCoins directly then instead of old overpriced equipment

Most likely used as well. I have a feeling BFL just delays all the release information of their products so they can get some mining time in. Most companies do this now which is sad. I would suggest to buy from a company with a reputation to protect and that have products in stock.
