Both companies will be coming out with something marketed competitively against the market leader, Sony's a7III. Probably the price will be lower, since neither of them will be able to match Sony's performance, so they will need to come in at a lower price point to compete. The a7III pricing was probably set at what it is as a pre-emptive shot by Sony, to make the introductory FF cameras from Canikon a bitter pill to swallow. It is unlikely that the high end DSLR set will be willing to part with their systems for a new MILC mount, so they will need to start off at the low end IMO, and that creates certain limitations. That is what I think will happen.
Despite Sony being (supposedly) technological superior for the last 5-7 years they have not made any real dent in CaNikon sales positions. This demonstrates two things: firstly that CaNikon have a massively loyal following, and secondly that the much-trumpeted benefits of mirrorless and all the gizmos that SOny introduce are not as important to the market as a whole as people like you like to think.
So do Canon need to be 'competitive'. It depends what you mean by competitive. People don't buy into a camera, they buy into a system and in the case of Canon that means ergonomics that people know and trust, it means a level of support that amateurs and pros can rely on, it means access to all the lenses and accessories (flash, remote controls) that you need to cover any photo situation, for many pros it means excellent telephotos and super telephotos.
Sony has caught up in many of those factors but only in the last 2 years - and because it is so recent they do not have a track record yet that people can say 'yep, Sony is there'.
So, for Sony the body is everything to get people to buy into it. For Canon it is about the least important. So all they need is for the body to fit within the current Canon system, provide continuity so people don't need a whole new learning curve and it needs do the things that 95% of the people need it to do....which is the basics.
Things like auto-focus bracketing (now seen on the D850) is something that makes people think 'that's cool' but in reality very few will use.
I guess you could say, that Sony is great body but as a system needs to step up its market approach to become competitive.
