Some updates regarding one of NGOHQ's previous article about the 7800 Ultra:
We currently have no information regarding the specifications and clocks except of the amount of memory and the core. NVIDIA has cancelled the name, but not the card. If this theory is true like we believe it is, NVIDIA can surprise us all with the pearl of the GeForce 7 series pretty soon. However another option with lower possibility is late release of the “Ultra” card but it will undergo a name change.
