Replacing old weapons, ATi is going to finalize the specification and designation of RV560/570 in the coming weeks. RV570 is to replace X1900GT with the same performance but a lower cost. RV570XT is probably designated to X1900GT, same with R580GT, or a new X1950 family.
With regard to the previous ATi roadmap from Gecube, sources indicate that RV560/570 are neither 12 Pixel Shader Processor nor products based on RV530 (Radeon X1600 family) plus CrossFire Compositing Engine. In addition, to complete with nVidia 80nm G73-B1, which supports HDMI Signal Mixing and is expected in production in Q4, ATi is going to release RV550 to give HDMI Signal Mixing support to HTCP.
