Canon has just announced a new full frame mirrorless camera with new lenses available.

It appears to be the same 5D4 sensor with on sensor phase detect autofocus points added. But it may well have excellent image quality.
Articulated 2.1 mp screen, 3.7 megapixel electronic viewfinder, world's fastest AF system plus AF that works in very dim light with an F1.2 lens.
Its the first Canon camera I have seen for a long time I am interested in. I think they have done a good job here.
Nikon also has released 2 full frame mirrorless cameras as well boasting basically Sony sensors 24.5mp and 45.7mp and lots of features. Notably built in intervalometer and time lapse.
Panasonic is releasing a full frame mirrorless on Sept 26 so a lot is happening in camera world at the moment. Fuji is releasing a sensation XT3 with up to 30 frames per second no blackout.
Sony is about to release a high end APSc mirrorless and has a new version of its low light A7Siii soon to be released.
Sony has had this mirrorless full frame market to itself for the last 5 years and has taken a lot of market share of both Canon and Nikon. Canikon seems to be mainly making sure the defections are stopped with these releases.
Whilst neither seems to have really topped Sony's models particularly (in some regards yes and others no) they all seem like intriguing and interesting cameras.
We are lucky to be spoilt for choice. If you have never used a high end mirrorless camera be prepared to not use your DSLR again. Some like the optical viewfinders and have big hands and like the large form factor but many get hooked on the electronic viewfinder and all the benefits it brings.
Plus the small size and light weight (easier on light portable mounts for nightscapes).
