I agree, the right move is to say nothing. You just need to make sure that you both don't judge each other on your parenting styles, turn it into some subliminal competition, and end up harboring resentment towards each other for it. Then the resentment starts to impact how you view the children.
There will definitely be a time and place for you guys to come together on it which I think will happen naturally as your R unfolds and you both are on the same page about the future
