I don't know if PS4-XB1 ports are neccessarily out of the question in a unified platform structure either.
PS4-XB1 are pretty dated tech for 2016 standards, and mobile tech is starting to catch up.
You could have a teraflop plus chip based on mobile tech in a console that has the benefit of being plugged into the wall at all times and you could have a little brother portable version of that chip for the handheld.
If it's getting Dragon Quest XI and they are looking at Final Fantasy XIV, perhaps there is more horsepower than we think.
