OK, expanding the roadmap by including competing products from nVidia and ATi dual GPU solution, will it look like it ?

GT200 --> RV770 & R700 --> GT200b (GT206 ?) --> RV790 & R7xx --> GT212 --> RV870 & R800 --> GT300

The timeframe seems quite coherent. With GT212, i think nVidia has a chance for a dual GPU card too, considering GT212's less than 300 mm^2 die size area.
