According to Canon Rumors, the next addition to the Zeiss Otus line of high performance, manual primes is going to be an 85mm. The 85mm Otus will be like the 55mm in that no corners will have been cut in optical design and build. As of yesterday, the Otus 55mm is still the king of all 50-ish-mm lenses according to DxO (even the Sigma).
Hopefully we'll see Sigma retaliate with a 85 f/1.4 of their own, the current model is looking a little long-in-the-tooth.
