Yeah, they confirmed several months ago that they're going to include Triple Triad as a card game, possibly coming when they implement the Golden Saucer.

Q30: Are there any details that you can reveal about the Gold Saucer?
A30: We are planning to implement chocobo racing and the “Triple Triad” card game. Other than that, we have plans to implement a basketball shooting-like mini-game and an active event that will take place within the Gold Saucer. Please stay tuned!
