Corporations cannot commit treason, nor be outlawed, nor excommunicated, for they have no souls - Sir Edward Coke
ATI has been pushing hard for January but it seems it won't make it. Nvidia is also preparing the faster version of G80 for around Cebit time but this is nothing new, as Nvidia traditionally likes to spoil ATI's launches.
The launch and availability will take place together, so as soon as DAAMIT officially introduces the card it should be widely available. It is an 80 nanometre part and should prove to be very powerful DX 10 hardware. It will arrive around the time of Microsoft's Vista DirectX 10 announcement, or shortly thereafter. µ
