Well, it appears that the excitement (?) was premature and misguided:

 

A recent report at PetaPixel that seems to have gained traction suggests that the Canon EOS 6D Mark II will be a full frame mirrorless camera. This report is 100% untrue, the EOS 6D Mark II, which we expect to announced around May/June of 2017, will be a DSLR.

As for a full frame mirrorless camera, we haven’t seen any solid evidence of one coming in 2017.

Some may say: well, this is only a rumour. But so has been the original statement, so it's just a war of words. My take: I don't believe in a Canon - or Nikon - FF mirrorless (just yet); people have indulged in wishful thinking too much.
