Now that G80's finally off its leash, the anticipation towards ATI's responding DirectX 10 cards (codenamed R600) continues to grow stronger, and the last I heard they'll be likely to debut no earlier then february next year.
VR-Zone have discovered some interesting news regarding the development of R600, with an apparent redesign in place to try and shorten the physical size of the card and improve upon its cooling properties.
A re-design for R600 card and cooling is currently underway to make it shorter and better cooled. The original R600 card design is 12 inches long and ATi is probably trying to shorten it to at least 8800GTX length. The Inquirer has recently reported ATI has already produced some first R600 cards that are clocked lower to send out to game developers for debugging and optimizing their games for R600. The R600 card we seen will conform to the new PCI-SIG graphics spec of delivering 225/300W power for high-end graphics cards. Therefore it will have a new 2x4 pin connector for additional power on top of the current 6-pin connector.
