Looks like ATi will go through a die-shrink before they intro their next graphics core. nVidia's plan is the other way around. Should make for an interesting summer...

"G71 should be Nvidia's last Geforce 7 generation card, and after than it will move to G80, the eight generation powered with Unified Shaders. ATI, on the other hand, is preparing to move to 80 nanometres first."
