Canon filed a patent for a 50mm f/1.4 lens. The patent literature refers to AF speed improvements.
The current EF 50mm f/1.4 was released back in 1993. A replacement could be on its way. It’s likely we have the patent for Canon’s next EF 50mm f/1.4 lens.

Roger Cicala of LensRentals did a quick test of the Sigma 24-35mm f/2 DG HSM ART lens for full-frame DSLRs. From the conclusion:
[…] the glass here is definitely way more than half full. We have, for the first time, a modern zoom lens that reaches f/2.0 aperture and is wickedly sharp. That’s an amazing thing all by itself and this is a unique optic. What is really amazing to me is that it sells for $1,000. That’s way less than either of the f/1.4 primes we tested against it, less than two of the f/2.8 primes, and less than an f/2.8 24-70mm zoom (granted that zoom does go all the way out to 70mm).
He also points out that the Sigma won’t probably be everyone’s lens. It’s not fast enough for those shooting with a prime lens (they’ll always choose f/1.4 lenses) nor does it have enough zoom range to get interesting as such. It’s another masterpiece by Sigma, that’s sure, and it comes at the usual exciting price tag below $1,000. Read the article at LensRentals.
