Looks like I know what I'll be seeing at CES next month when I meet with AMD. Today, AMD announced a new family of video cards in the RV680, RV635, and RV620. All three are built on the 55nm process. It seems the cards have not one but two GPUs on them with the RV680 most likely holding two RV670 GPUs onboard. The cards support the new CrossFireX feature which can pair up up to four cards. We'll know more once the product hits in a month.
