Yeah, as mentioned before, Nvidia's DSR is just a fancy marketing name for Super-sampling, a technique that has existed for many years.
As resolution increases, super-sampling types of AA (Including MSAA) will become obsolete in my opinion. We'll just need some post-AA to make some finishing touches on the image quality.
