This is really frustrating. nVIDIA now unlike previous years have kept control of leaks. Even the usual "insiders" have no idea what to expect. Its not too soon from november and all sorts of rumours are floating about. Not a single concrete leak on G92 or G9x.
The only thing i can think of so far that is concrete are:
the 1 teraflops figure, G92, 8700 series and 65nm.
The other things floating around are displayport, SLi 2.0, pure video 3.0, 512bit etc etc. Not really sure what to expect.
note - the latest conference held by nVIDIA reports a 2 billion dollars worth of profit by the years end.
