A patent for a Tamron 85mm f/1.8 VC has appeared. Is Tamron following Sigma and getting into the quality prime market, but with Vibration Correction (Image Stabilization)?

Canon's 85mm offerings, the EF 85mm f/1.2L II and EF 85mm f/1.8 could probably both use a refresh, though we haven't heard anything about either in a very long time. I can't see Canon ever adding IS to a fast (f/1.2) 85mm lens, but we might see something like an 85mm f/2 IS STM one day.
