Looking at the MTF, you are right, it falls off sharply in the corner at f/1.4, but that is not so unusual for a lens like this. The 50/1.4 AFD was like this at f/1.4, but by f/1.8 or f/2, it was already a lot sharper in the corners. Hopefully this will be sharp on center wide open, and then sharpen up very quickly across the field. I would also like to see the distortion specs, as that is something where a prime should offer quite an advantage over a zoom.
