That's not an exaggeration, it's actually probably a conservative estimate. The 50mm L 1.2 has a resolution of 1400 lpph average @ f/1.4, which translates to around 3.4 Megapixels of resolution. There is no recent retro focal design with aspherical elements that has a resolution of less than 2800 lpph average at f/1.4, which translates to 14 megapixels.
I believe that point and shoots to dslrs is a good comparison. Or more accurately, wide open the Sigma 50mm art will at a minimum have the same difference between its competitors in performance as a D800 with the sharpest lens available versus a smartphone camera.
Radiating, I really kind of see your point. If that lens wasn't a Canon L, I agree with you, it would have many fans fewer.
L lenses aren't just about optical quality, it's the whole build and reliability features which are designed into the lenes too. A 50mm f1.4 USM's build is a toy in comparision.
