Would it be a fair comment to say.
The reason behind nvidia having such a strong NDA and being so tight lipped with there information on the 470s/480s, has alot to do with the fact that ati where able to keep the development
of eyefinity a secret from nvidia right up to the card being released?

It just seems to me like nvidia are making the ponit that they can keep things on the down low as well if they choose to.
