Bryan Carnathan's most excellent TDP website has posted a very nice head to head of IQ of the Sigma 50 Art against 7 similar focal length primes, including the Canon L, Canon 50 1.4 and the Zeiss Otus:

His IQ comparisons are fun if you haven't used them before. You mouseover the sample shot and the arrow indicator flips to show what image is being shown. You can change the aperture and see what changes, and he'll eventually even run the same test on crop body (note: he only has FF data on the new Sigma 50 right now).
By my eyes on these sample shots, the new Sigma Art thoroughly trounces the Canon 50L (as expected) and the Canon 50 F/1.4 (though it's pretty similar after F/4 or so). The Zeiss, to me, looks sharper wide open, esp. in the corners. Maybe that's what +$3k buys for you.
Of course, this is not the end-all be-all for a lens review. I'm sure Bryan will write quite an opus on this one in the next week or two.
But it's looking good. Have at it and see for yourself!
