I strongly suspect both Chocobo Racing and G-Bike are going to use the same engine, as created by CyberConnect2. So I actually would love to see, if not the first encounter, then later on that Zolom becomes a part of a chocobo or b-bike race. That thing moves FAST, and it'd be a big addition to that minigame if it becomes something that spans across the games, rather than just the beginning and in Gold Saucer. Considering how many locations they added for G-bike Mobile, I can totally see it being a means of fast-travel between cities.
