I don't expect the GTX260 or 275 to go very far, but the higher-ends should drop like rocks. From what I remember from that pic that was posted (it almost looked like a Russian nVidia specs page...), the GTX360 will be $299, which, if the performance is everything the hype says it is, will slaughter the 5800s. Don't take my word for it, though, that's just speculation (like most recent things regarding Fermi...).
