There is a chip that should replace Brodway, a 40nm 800-shader chip in the high end area, and there is an upcoming chip that should replace Madison 40nm 400 cores / shaders chip in mainstream. The last new chip is a replacement to the Park series that until now have 80 Shader cores for entry level market.
The new cards will bring Eyefinity to notebooks and you should be able to connect many displays to notebooks based on these chips. All these chips are 40nm and are developed under Vancouver master codename.
All these chips should be compatible with ATI’s implementation of Optimus, automatic graphics switching. Let's hope that this can help ATI to gain some design wins as Nvidia really got a lot of attention with Calpella designs and its Optimus capable chips.
