I was over at AnandTech forums reading up on this thread and they were pointing out how the GeForce FX Ultra 5800 is still to be released late February. His email is posted on the net here at NVIDIA Support Website. Here's what it comes down to.

"NVIDIA's GeForce FX Ultra 5800 and the GeForce FX 5800 are still targeted to be in retail in late Feburary."

Interesting none the less, however take it with a grain of salt. I'd say lets wait and see.
