I don't think this should be really new to anyone. It has been stated before that the market makers are adjusted to provide liquidity for people to cash out their shares when information has become more certain about sales.
People bought up Madden 07 Xbox 360 stock to as the sales info came in each month. When the data showed the stock was worth at least 160 DKP, sufficient liquidity was provided by the market makers so that the people could sell shares at at least 160 DKP. This was an adjustment of QTY and not the PRICE, but an adjustment was made from the NPC market maker's usual programming to take into account fundamental information.
In fact, basically nothing is different. Just consider the market makers submit bid and ask orders based on some formula usually and when news comes out they may adjust their orders appropriately. Whether the change was made by software or some human being doesn't really matter. I'm sure many market makers on Wall Street usually use software to make markets and then manually make adjustments when there is fundamental information.
