A long time ago, even before Alpha, Tanaka mentioned something along the lines of Magitek armour might be in the offing - when I eventually saw the opening movie, I guessed that Magitek had been the principle inspiration for the design of the Garlean Empire's kit, but I'd throw a mention about Magitek back in there just to keep the idea in the mix. (Edit: Just spotted Magitek mentioned above. Still, +1)

On the subject of Chocobo's, I'd like to see hitching post facilities added to the major Aetherite camps. We could ride between camps and hitch the chocobo up and do some leves, then unhitch them and ride off to somewhere else. You'd need an ability to summon them in the field zones though. And, I know we have Retainers, but I think some way to integrate those inventories would be helpful - possibly have a (long-missed) Delivery box system, whereby stuff you are waiting for gets sent to your chocobo's post-bag.
