NVIDIA Introducing a New Anti-Aliasing Algorithm with Kepler?

Reliable sources indicate that NVIDIA could introduce a new anti-aliasing (AA) algorithm with its Kepler family of GPUs. There are already plenty of AA algorithms which have been introduced with recent generations of GPUs, including FXAA, which have enabled higher levels of image quality, while not being as taxing as MSAA. This leaves only one area in which a new AA algorithm can take shape: to raise the image quality bar higher, while lowering performance penalty.

In a screenshot, probably sourced from NVIDIA's GeForce Kepler press-deck, this new algorithm is compared to 8x MSAA, in which it appears to give superior image quality. We know that 8x MSAA can be taxing, the kind of image quality we're seeing with this mysterious AA algo 'looks' taxing with available technology, unless of course, NVIDIA developed a silver-bullet in its new algorithm, which provides stunning image quality while not being too taxing on the GPU's resources.
