I expect to have a TDP of 225W, clocked at 700Mhz...
It would have even lower temperature than GTX 580.
So we will have GTX 480 performance at lower power consumption and heat.
And may be even higher frecuencys in overclocking...950-970Mhz.
Price i expect to be 369-399$.
Next would be GTX 560, 384SP, based on GF104, at 300$.
