The sell off was today but they will announce the winners of the auction tomorrow. It could have affected the price perhaps.
They don't announce the winners. A winner may announce themselves, but maybe not. Occasionally someone will say the price of their losing bid. The coins won't move until monday.
I actually think they are pretty unrelated, other than giving some courage to the bears because of the lower numbers of bids and bidders. OKcoin going down was probably a much bigger factor in today's dumpfest.
