From what I saw Nvidia gives a lot to the game devs. Did you read that bit about them suppling the devs with high end graphics cards, systems, etc and the company was only a start up. I don't really blame Nvidia as much after reading all of that. I would be a bit peeved if ATi always let Nvidia work out the details and then they reap the benefits.
Like Taggart said, moral of the story:
Nvidia is getting pissed and doesn't want their work to contribute to Ati.
Ati needs to get with the game and work with the devs.
Epic should have implemented AA in the first place.
You forgot one:
Great super hero games can be made if Hollywood doesn't interfere.
If we hit that bull's eye, the rest of the dominoes will fall like a house of cards. Checkmate.
