According to VR Zone the upcoming GeForce 8800 GT from NVIDIA will have 112 stream processors. The guys also discovered the shader clock will be 1.5GHz:
CJ did some nice analysis on the Nvidia's strategy here on why is there a new 8800 GTS SKU. He revealed that there is a shortage of GTX cores but plenty of GTS cores going around that didn't quite make it as a GTX. So if you launch a new product that is faster than a 8800GTS, no one will buy the more expensive GTS unless you up its stream processor count for higher performance. Also with a 320-bit memory interface, it certainly perform better at high resolutions and with lots of AA/AF/HDR. This way Nvidia can still get rid of the inventory.
