January 20, because Vista arrives Jan 31. You can expect ATI to bring out it's full line of DX10 cards mid-January. Nvidia will also introduce it's low- and mid-range cards about the same time. Both companies know that consumers and small business will want/need Vista cards, and relatively damn few people buy a video card that costs more than $350. Hence, there will be a large selection of cards available at Vista's launch. Neither vendor is going to want to miss out on the first wave of upgraders.
