Just spotted this bit of Info over at Overclockers.com.

Intel said that they were going to work on power reduction in its next stepping of the PIV.

Well, the D0 stepping is now available for socket 775 PIVs, and so are the datasheets for them. If you look at page 74 of the datasheet, you'll find out that D0 stepping chips have a Thermal Design Power rating of 84 watts up to 3.2GHz, and 115 watts for CPUs up to 3.6GHz.
