A couple of images of a Leica full-frame mirrorless camera have been posted on a Japanese website, which claims the subject of the photos is the Leica SL2. The German manufacturer released the SL (Typ 601) in October 2015, which was generally well-received but noted for its high price tag and its cumbersome build.

IMO it looks nicer, the first generation looked as ugly as 1st gen A7.
