It's pretty much a sure thing that Nvidia will release one,the thing is that even at 55nm,it still yeilds a die that's about 400mm^,so still quite large and fairly expensive to make,and there's the extra complexity in terms of PCB design given the amount of pins used on the GPU package and traces needed on that same PCB given the 512 bit bus needed for each GPU.


Add the 1 GB GDDR 3 memory for each GPU in there,and the cooling and power requirements of feeding 2x 400mm^ dies packing 1.4 billion transistors each,2 GB of ram total,and use a cooler no bigger than the one used in the 9800GX2 so users can actually fit that thing in their cases..[wink]


Then there's the cost of the thing,since it'll be more expensive to make than the 9800GX2 for sure,so quite a lot of challenges to tackle..
