No pricing yet on the Sigma, but it's sure to be less than $4,000.
Petapixel concludes that the Sigma handily beats both the Nikkor and Sony 50mm f/1.4 lenses (no Canon in the test.) They conclude:
It's nice to see a 3rd party challenge the major vendors, let alone Zeiss. It'll be interesting to see DXO numbers at different apertures and how it handles contrast and color rendition, but it's looking very interesting.

To our eye, the Sigma lens more than keeps up with the Otus and obviously outperforms the other two lenses, particularly in the corners.
