Could even be the unneutered card that we all originally expected. I'm fully expecting it to be the 685 instead of the 690... unless NVIDIA believes it good enough to warrant the 780 moniker. In any case, you'd expect a x90 or x95 card to be dual-GPU.
With a teaser image that dramatic, it's probably referring to the GTX690. I have no idea how Nvidia's planning to supply GPU's for these upcoming products, all of which are based on gk104 (GTX690, GTX670ti, GTX670), seeing how they can't even properly supply the GTX680 at the moment.
