Nvidia doesn't hold grudges like AMD does.
I'm sure you know more about this than me, but didn't nVidia refuse to let them have any of the 400 and 500 series because they were pushing the HD5000 series? Still, that's the only example that I can think of while you can probably list a few more for either company (nVidia or AMD).
Hopefully they can get everything worked out, because those cards are quite an investment to lose.
