The Reg has heard rumblings that we'll see the chips next month sometime. I guess their die-shrimk's going over well.... Not only will they be 80nm R500-series parts, the Reg has this bit of info as well:

"The cards are expected to be the first to sport ATI's new internal CrossFire connector, which differs from Nvidia's SLI link by placing two, not one, proprietary connectors on the top of each add-in board."
