If you are ever going to say something, I think now is the time (well, wait until after Christmas). That way, they can easily include him on the actual invitation if they want, without any drama.
If I were you, I'd talk to the mom (not the bride-to-be) and just casually say "Hey Minnie, we got the save the date to Daisy's wedding. I just wanted to clarify that it's just the three of us, and that Mickey isn't invited."
And then accept whatever answer she gives.
