Well actually the engineering code names do in fact have more significance than the product name. Products can be rebranded, and shifted around all of the time, but the internal codes are not. Nvidia has consistently used a similar internal naming system for their dies for as long as it is relevant, however product names have shifted and changed meaning multiple times. We know that GK100 existed, we don't know why it was scrapped, but we can speculate that it was because it was broken much like GF100 was at the time. We can also speculate that unlike Fermi, Nvidia had a high performing midrange product ready that could fill the high end spot for a while to hold back the competition rather than being 6 months late with an immature architecture again. Knowing what they knew, they probably decided to skip the whole nightmare of trying to release that chip, and just use it as a reference for the GK110 revision.
It's probably just like Fermi, except they are skipping right to the 580 equivalent part, and never letting the public see the less refined 480 equivalent. With this in mind, it should be clear to anyone that GK104 is in the middle of what Kepler is capable of as an architecture, and that Nvidia while is probably a few more months away from being able to deliver a working GK110 chip, they are working on one, and they will release it within 6-9 months. Who knows what they will call it, I don't really care, all I know is that GK104 is ripe for rebranding as midrange as soon as the big boy does drop.
