Business wise it's better to ship many GTX and GTs and sell them in quantities than to release a limited but faster Ultra. We learned that Nvidia shipped a few tens of thousands of GTX and GTs already and it has been shipping in numbers ever since. Last thing you want is to upset people with releasing Ultra, a card that would be marginally faster than G70 and likely to create more problems than solve them.
In that light a very limited but available R520XT might be a Yule winner and best performer and Geforce 7800 GTX is here to stay. At some point Nvidia has to update it to a 512MB memory version but that’s about it. The key problem for ATI is that it cannot ship a few tens of thousands of those units until December, no chance at all, and Nvidia can reach and beat those volumes with its highly available GTX part.
