Cloud Motorcycle Mount and Buster or Fusion Sword

[Enkidoh]

SE have already stated those images going around of Cloud's Fenrir motorcycle in the game was nothing but a joke mount made by the development team and that they are not actually adding it to the game for players (one reason is because it looks downright stupid travelling at the same speed every other mount in the game travels at, to say nothing of the very concept of such a futuristic bike in a world that still uses wooden sailing ships and chocobo-hauled carriages for transportation.). So it will never be in the game.

And the Buster Sword already is in the game - but not as a weapon. It's actually the level 2 melee Limit Break (as you're aware). Thus that too will never be added as a weapon in the game (unless SE then go back and change the Limit Break animation, something I think is highly unlikely). Either way, I'm really sorry to say but your wishes will probably never be granted sadly.
