PC Perspective has taken the information that AMD is providing today at the official Barcelona and compiled it together in a preview article.

This smells VERY similar to the recent HD 2900 XT launch that AMD's GPU division had earlier in the year -- because their product couldn't meet the performance/watt levels necessary to compete against the high end NVIDIA products, they aimed a lower priced product line with their top part. They seem to be doing that here with Barcelona as well...
