It's getting super hard to predict what Canon will and won't do because it's been so long since they've released any new tech, and they never give any specs. With that said, anything less than 1.6x crop sensor size, nobody will buy it. Small chip, fixed lens cameras are history.
I don't think Canon would do something that dumb, but yeah.... until Canon start releasing new technology again, it's impossible to predict.
Personally, I think it will be released in 2020.
