According to DailyTech AMD is delaying their integrated chipset (fromerly the RS690 chipset from ATI) due to some HDCP issues. 
AMD was expected to release its long awaited ATI RS690 integrated graphics chipset shortly after the AM2 launch in mid-2006. Since the AMD acquisition of ATI, the chipset has since been renamed to AMD 690. The AMD 690 chipset is currently in its A12 stepping, which is near final silicon. However, AMD has run into a slight delay with the AMD 690 chipset.

AMD is asking major members of the Chinese media to remove all references of the chipset in articles from their publications by Christmas day or be left out when it comes to review samples.

Motherboard samples based on the AMD 690 chipset were expected early next year. Manufacturers were expected to have motherboards ready to be shipped as early as January 2007. Nevertheless, it appears AMD is waiting until early February 2007 to launch the long-awaited and delayed AMD 690.
