Haha, no, I dont work for nividia, im just applying a bit of common sense to the situation. This is virgin, undeveloped tech, dont forget, and its quite obvious the competition is rattled (see the last 20 pages).
It's not really common sense as such, no one is arguing the merits of GPGPU technology (no one who knows what they're on about at least), but CPUs as they are simply aren't good enough to do the tasks handled by GPGPUs.
That's the purpose of them, it's not really a CPU replacement, it's a compliment if anything, it's just nVidia are using marketing to try and tell people that the CPU isn't important in the hope that they buy a new nVidia graphics card instead of upgrading their CPU.
As for "virgin undeveloped tech", again it's simply untrue.
This has been in development for a very very long time, they've been tweaking it for nearly a year already, drivers too, they've simply been having hardware problems where they couldn't viably produce the cards.
