B1 will make some difference, but not a lot. It might just get them up to 750 mhz 512 shaders like they planned, but then thats only going to be ~10% faster than the GTX 480 is now. It will still be hot as it is now, if not hotter. 32nm was canned btw, have to wait for 28nm, which is a long way out, 2011 at the earliest looks like now.
So basically, if you're waiting for a real NV refresh, you're looking at about a year.
