Them doing this signals to me that the RAM pricing isn't going to go back to normal for quite a while. They've been riding this out, likely through long-term contracts. They also don't seem to be the sort of company to lower prices (unless demand REALLY falls off a cliff with the new prices, maybe not even then).
Chances are that these prices indicate a ~18mo contract at the new prices, though we don't know for sure.
But it sure sounds like this is just the new normal for at least the next 18mo.
