At AMD's Phenom launch event in Warsaw, FUD Zilla learned the first AMD processors with DDR3 support will arrive in the first half of 2009:
Another Star, that I’ve mentioned more than a year ago, will sit in socket AM3 and it supports Hypertransport 3. It supports DDR3 1333, dual processor power planes and serial VIDs. It is scheduled for 1H 2009.
It has a new thermal monitor and calls it Thermal sence interface (TSI) and just as AM2+ based Stars it might need a 8 Mbit bios. It will have the same maximum power delivery.
