I'm pretty sure he said all of those are going to be included.
As for romance, I think it would be nice if you had the option to chose from a selection of first ladies/first husbands who you previously romanced, married and is now your partner, and then you can choose to either be a strong dependable power couple on the world stage, or risk having affairs and dna on dresses.
That said, it might be interesting to have the option to be a single president too, given that the world would talk about it. As for romance options outside a first lady (whether or not these are affairs or not) I would imagine the logical ones would be a security guard, the chief of staff, personal secretary, maybe some non white house types like a reporter?
Oh and it would be fun to have something at the end to compare to which president you are most like. Me, I'll be Teddy.
