Possible locations of 2007 WD5 relative to Mars on 30 Jan. 
2008. This NASA/JPL illustration is from Dec. 21st.

The NASA/JPL NEO Program Office reported yesterday that with further analysis, including new observation from Calar Alto Observatory (see yesterday's DOU MPEC), Mars impact probability has decreased to "1-in-40 odds" for 2007 WD5 three weeks from now. See the NEOPO's Asteroid 2007 WD5 page and A/CC has more news links here. Further observation has been reported today. The above NASA/JPL illustration of positional possibilities is from Dec. 21st.
