I found no mention of Golden Saucer in any Live Letter posted on this site. I found one mention so far about mini games.

Q: Are you looking into mini-games or other elements where free company members can gather and play?
A: I think some staff members are starting to think about a card game…

Only time I've seen Gold Saucer mentioned was in threads like this making speculations. As I said, the Platinum Mirage exists, isn't open to the public according to the NPC running the desk, and is a "Minigame-esque" area based on the description the NPC gives you.
