hehe. Not quite. Pros do what makes them money. Hobbyists do what they like.
Other than that I agree: most likely Canon will launch a big, fat, 1Dx-type sports MILC with regular EF mount targeted at pros [2018]. Super expensive of course. AF will be "adequate" = similar to EF glass [USM] in live view mode on a 1Dx II.
Next [2018/19], Canon will likely launch and sell new versions [EF] of f/2.8 L zooms and hi-end primes ... with Nano-USM [and IS ... e.g. EF 24-70/2.8 IS USM]. Lens prices will of course be raised from around 2k to about 3k.
Then [2019] they will launch a Sony RX1R II type ultracompact FF camera with bolted-on zoom 3x lens. Powershot G1X III with FF sensor. Ccurved sensor possible, but likely only in Mk. II or Mk. III version ... not in 1st gen.
And only thereafter [2020] will Canon finally come up with the slim, new mount [EF-X?] system to cater to me and all the other people who want a fully capable FF MILC in the smallest possible form factor. Price/performance roughly in 5D territory. Plus a limited line-up of super compact moderately fast, around f/2.0 primes. Plus some f/4 zooms smaller than current EF versions [16-35, 24-70, 24-105].
Things may happen faster, when Sony A7 III/R/S hit the market and get traction and more so, *IF* Nikon brings a killer FF MILC system
